η3-allyl-monocyano-tricarbonylmetallate und η3-allyl-monoisonitril-tricarbonyle des mangans und rheniums

Abstract The reactions of η 3 -C 3 H 4 RM(CO) 4 (η 3 -C 3 H 5 = allyl for R = H; η 3 -C 4 H 7 = 2-methylallyl for R = Me; M = Mn, Re) with NaN(SiMe 3 ) 2 lead to the formation of the η 3 -allylmonocyanotricarbonyl metalates [η 3 -C 3 H 4 RM(CO) 3 CN] − which can be converted into the corresponding isonitrile derivatives η 3 -C 3 H 4 RM(CO) 3 CNMe or η 3 -C 3 H 4 RM(CO) 3 CNSnMe 3 by treatment with [Me 3 O]BF 4 , MeI or Me 3 SnCl. The new complexes are characterized by their IR and 1 H NMR spectra, and in the case of the isonitrile compounds also by their mass spectra.
