An improved process is disclosed for preparing aromatic fluorides by diazotization-fluorination in hydrogen fluoride wherein the diazotized reaction mixture includes an oxidizing agent such as nitrosonium ion from excess diazotization agent. The improvement includes, prior to decomposing the diazonium fluoride, adding to the diazotized reaction mixture a member selected from hydrazine, aromatic hydrazine, semi-carbazide, thiosemicarbazide, acid salts thereof, sulfur dioxide, sodium sulfite, and sodium bisulfite to remove at least a portion of the oxidizing agent. Urea was found to be ineffective.

The present invention relates to processes for producing chlorinated alkane compounds having acceptably low levels of oxygenated impurities.Haloalkanes find utility in a range of applications. For example, halocarbons are used extensively as refrigerants, blowing agents and foaming agents. Throughout the second half of the twentieth century, the use of chlorofluoroalkanes increased exponentially until the 1980's, when concerns were raised about their environmental impact, specifically regarding depletion of the ozone layer.Subsequently, fluorinated hydrocarbons such as perfluorocarbons and hydrofluorocarbons have been used in place of chlorofluoroalkanes, although more recently, environmental concerns about the use of that class of compounds have been raised and legislation has been enacted in the EU and elsewhere to reduce their use.New classes of environmentally friendly halocarbons are emerging and have been investigated, and in some cases, embraced in a number of applications, especially as refrigerants in the automotive and domestic fields. Examples of such compounds include hydrofluoroolefins (HFOs) such as 2-chloro-3,3,3-trifluoropropene (HCFO-1233xf), 1,3,3,3-tetrafluoropropene (HFO- ...

The present invention relates to a process for preparing N-(5-chloro-2-isopropylbenzyl)cyclopropanamine by hydrogenation of N-[(5-chloro-2-isopropylphenyl)methylene]cyclopropanamine over specific platinum catalysts.Preparative processes for brominating strongly deactivated aromatics such as p-alkyl-substituted nitrobenzenes or nitrobenzene itself are described in the literature. The bromination of p-nitroethylbenzene by means of iron and bromine has been described with very low yields (55% yield of crude product and 34% after distillation) and with long reaction times of over 24 hours (1950, 72, 2804). The bromination of nitrobenzene by means of iron and bromine is described with a yield of always 60-75% of isolated compound (cf. 1941, Coll. Vol. I, 123, ibid. 1928, Vol 8, 48). A further possible way of brominating deactivated aromatics by means of potassium bromate is known (1981, 46, 2169-2171). However, reactions are problematical from a safety point of view because of the decomposition of potassium bromate in over 70% strength sulphuric acid solution. Furthermore, the bromination of p-nitrotoluene or nitrobenzene by means of N-bromosuccinimide in half-concentrated sulphuric acid is known (2006, 8, 645-6471965, 30, 304-306). However, this reaction requires N-bromosuccinimide as brominating reagent. Dimethyldibromohydantoin is found to be significantly more efficient (cf. 1994, 67, 1918-1921). However, trifluoromethanesulphonic acid, a very expensive reagent, is used here as proton source, which ...

Alkenes as alkyne equivalents in radical cascades terminated by fragmentations

Номер: US20160347778A1

Disclosed are methods for rerouting radical cascade cyclizations by using alkenes as alkyne equivalents. The reaction sequence is initiated by a novel 1,2 stannyl shift which achieves chemo- and regioselectivity in the process. The radical “hopping” leads to the formation of the radical center necessary for the sequence of selective cyclizations and fragmentations to follow. In the last step of the cascade, the elimination of a rationally designed radical leaving group via β-C—C bond scission aromatizes the product without the need for external oxidant. The Bu 3 Sn moiety, which is installed during the reaction sequence, allows further functionalization of the product via facile reactions with electrophiles as well as Stille and Suzuki cross-coupling reactions. This selective radical transformation opens a new approach for the controlled transformation of enynes into extended polycyclic structures of tunable dimensions.

Continuous method of obtaining chlorfluormethanes or chlor fluorethanes

Номер: SU1577693A3

A continuous process for fluorinating haloalkanes containing at least one nonfluorine halogen atom wherein antimony pentachloride is reacted (A) with HF to produce an antimony chlorofluoride. The antimony chlorofluoride thus produced is then transferred to a separate reaction zone (C) where it is reacted with the haloalkane, thereby replacing a portion of the nonfluorine halogen in the haloalkane with fluorine of the antimony chlorofluoride.

Liponucleotide-containing liposomes

Номер: US5223263A
Принадлежит: Vical Inc

Compounds are disclosed for treating AIDS, herpes, and other viral infections by means of lipid derivatives of antiviral agents. The compounds consist of nucleoside analogues having antiviral activity which are linked, commonly through a phosphate group at the 5' position of the pentose residue, to one of a selected group of lipids. The lipophilic nature of these compounds provide advantages over the use of the nucleoside analogue alone. It also makes it possible to incorporate them into the lamellar structure of liposomes, either alone or combined with similar molecules. In the form of liposomes, these antiviral agents are preferentially taken up by macrophages and monocytes, cells which have been found to harbor the target HIV virus. Additional site specificity may be incorporated into the liposomes with the addition of ligands, such as monoclonal antibodies or other peptides or proteins which bind to viral proteins. Effective nucleoside analogues are dideoxynucleosides, azidothymine (AZT), and acyclovir; lipid groups may be glycolipids, sphingolipids, phospholipids or fatty acids. The compounds persist, after intracellular hydrolysis, as phosphorylated or non-phosphorylated antiviral nucleosides. The compounds are effective in improving the efficacy of antiviral nucleoside analogues by prolonging the antiviral activity after the administration of the drug has ended, and in preventing retroviral replication in HIV infections which have become resistant to therapy with conventional forms of the antiretroviral agents.
