摘要：

The nickel-catalyzed reactions of 2-phenyl- and 2-(o-tolyl)-2-(phenylethynyl)hexamethyltrisilane (I and II) with phenyl(trimethylsilyl)acetylene at 180°C have been examined. The reaction of I with phenyl(trimethylsilyl)acetylene in the presence of tetrakis(triethylphosphine)nickel(0) gave 1,3-diphenyl-2-[phenyl(trimethylsilyl)methylene]-1,4-bis(trimethylsilyl)-1-silacyclobut-3-ene and 1,4,4-trimethyl-1,3,6-triphenyl-2,5-bis(trimethylsilyl-1,4-disilacyclohexa-2,5-diene. Similar reaction of II produced 3-phenyl-2-[phenyl(trimethylsilyl)methylene]-1-(o-tolyl)-1,4-bis(trimethylsilyl)-1-silacyclobut-3-ene and 4,4,5-trimethyl-2,6-diphenyl-1,3-bis(trimethylsilyl)-1-(o-tolyl)-1,4-disilacyclohexa-2,5-diene. The results of the reactions of I and II in the presence of a catalytic amount of the nickel(0) complex in the absence of phenyl(trimethylsilyl)acetylene are also described. © 1990.
