Synthesis, structure, and alkyne reactivity of a dimeric (carbene) copper (I) hydride
Organometallics, 2004•ACS Publications
The monomeric, two-coordinate carbene complex (IPr) CuO-t-Bu (1)(IPr= 1, 3-bis (2, 6-
diisopropylphenyl) imidazol-2-ylidene) reacts readily with silanes such as triethoxysilane,
forming a dimeric copper (I) hydride complex (2) with a very short copper− copper distance.
Hydrocupration of 3-hexyne by 2 affords a monomeric copper (I) vinyl complex.
