Summary

Treatment of complexestrans-[M(CNBu-t)2(dppe)2][(1) M = Mo or W, dppe = Ph2PCH2CH2PPh2] with protic acid gives a mixture of the aminocarbyne complexestrans- pluscis-[M(CNHBu-t)(CNBu-t)(dppe)2]+ (2) and the hydridocompounds [MH(CNBu-t)2(dppe)2]+ (3), whereas reaction with an alkylating agent (R+) appears to give the dialkylaminocarbyne compounds [M(CNRBu-t)(CNBu-t)(dppe)2]+ (4) also as a mixture of thetrans andcis isomers.
