Abstract

By HIROSHI YAMAZAKI (The Institute of Physical and Chemical Research, Wako-shi, Saitama, Japan) ... Summary With a catalytic amount of dihydridocarbonyl- tris(triphenylphosphine)ruthenium, t-butylacetylene stereoselectively dimerises to trans-1,4-di -t-butylbuta- triene. ... THERE are several reports on the dimerization of mono- substituted acetylenes to disubstituted vinylacetylenes by transition nietal cata1yst.l We now report a novel cata- ...
