5-hexadiene (VII), respectively. Photochemical reduction of butane III with 2-propanol resulted in a preferential reduction of CBr bonds, and from 2,3-dichloro-1,1,2,3,4,4-hexafluorobutane (IX) thus formed, esters of difluoroacetic acid were prepared by dehalogenation of IX and subsequent oxidation and esterification of the product. The photochemical reduction of hexane IV gave a mixture of 79% trichlorononafluorohexane
