Abstract:
The hydrides (η5-C5H5)(CO)3MH (M = Mo, W) react with ynamines R′CCNR2 under mild conditions to form 1 : 1 adducts. According to the 1H and 13C NMR spectra depending on the metal and the ynamine substituents carbene acyl chelate or complexes with η3-aminoacryloyl ligands are formed: A Dicarbene chelate compound is obtained by alkylation of I, R = Et, R′ = Me. CC-η2 keteneimmonium complexes are formed in the reaction of the phosphite substituted hydrides (η5-C5H5)(CO)2P(OMe)3MH (M = Mo, W) with MeCCN Et; an intermediate 1-aminovinyl compound has been isolated.
