The reaction of (IPr) CuO t-Bu (IPr= 1, 3-bis (2, 6-diisopropylphenyl) imidazol-2-ylidene) with
triphenylstannane forms a stannyl complex,(IPr) CuSnPh3, by deprotonation of the tin−
hydrogen bond. This stannyl complex reacts with CO2 to afford (IPr) CuO2CPh as the sole
copper-containing species. A tin− carbon bond in (IPr) CuSnPh3 also undergoes facile
cleavage by mild acids such as 2, 4-lutidinium chloride.
