Claims6
A process for preparing a cis-olefinic compound from an acetylenic compound comprising contacting an acetylenic compound with hydrogen under conditions suitable to give a cis-olefinic product in the presence of a catalyst prepared by contacting an alumina-supported nickel arsenate with at least one borohydride compound;
- wherein said at least one borohydride compound conforms to the following formula:
- M(BH.sub.4).sub.n
- wherein M is a monovalent or divalent cation selected from the group consisting of:
- NR'4, wherein each R' is independently C.sub.1 through C.sub.10 alkyl,
- cycloalkyl,
- aryl,
- aralkyl and alkaryl;
- alkali metals;
- and
- alkaline earth metals;
- wherein n=1 if M is a monovalent cation and n=2 if M is a divalent cation.
