Provided is a method for producing 1,3-butadiene that enables 1,3-butadiene to be obtained in a high yield while preventing abnormal reaction of a fraction containing vinylacetylene in high concentration. The method for producing 1,3-butadiene is a method for producing 1,3-butadiene from a fraction produced in separation and recovery of 1,3-butadiene from a Chydrocarbon mixture that includes: adding a diluent to a high VA fraction containing vinylacetylene to produce a diluted fraction; and subjecting the diluted fraction to hydrogenation treatment to produce 1,3-butadiene. Substantially only a low VA fraction is used as the diluent. The low VA fraction is a fraction that is produced in separation and recovery of 1,3-butadiene from the Chydrocarbon mixture and has a lower vinylacetylene concentration than the high VA fraction. 1.

The present application discloses novel amino-sulfide metal catalysts for organic chemical syntheses including hydrogenation (reduction) of unsaturated compounds or dehydrogenation of substrates. The range of hydrogenation substrate compounds includes esters, lactones, oils and fats, resulting in alcohols, diols, and triols as reaction products. The catalysts of current application can be used to catalyze a hydrogenation reaction under solvent free conditions. The present catalysts also allow the hydrogenation to proceed without added base, and it can be used in place of the conventional reduction methods employing hydrides of the main-group elements. Furthermore, the catalysts of the present application can catalyze a dehydrogenation reaction under homogenous and/or acceptorless conditions. As such, the catalysts provided herein can be useful in substantially reducing cost and improving the environmental profile of manufacturing processes for a variety of chemicals. 2. (canceled)3.
