| Research Abstract |
Syn addition of silyl copper species to an alkyne affords a silyl alkenyl copper intermediate. Then, insertion of carbon dioxide provides the corresponding copper carboxylate species. Thus, the first catalytic silacarboxylation of an alkyne has been achieved by utilizing silylborane as the silicon source under atmospheric pressure of carbon dioxide to afford the silalactone selectively in high yield.
