Abstract

Reduction of [Co(CO)4]- or [M(CO)3] 4 (M = Rh and Ir) with sodium in liquid ammonia, naphthalene- tetrahydrofuran, or hexamethylphosphoramide (only M = Rh and Ir) gives pyrophoric substances which provide the first main group 4 derivatives of [M(CO)3]3- (M = Co, Rh, and Ir) in 20-90% yields.

CHEM.COMM., 1977 reactive solvents. The high yields of derivatives of [Co-National Science Foundation for support, Steve Hentges (CO)J3-obtained from (I) strongly suggest that this for experimental assistance, and the N.S.F.-Undergraduate material is a monomeric carbonyl species. Also, since the Research Participation Program for a stipend to P. T. B. i.r. spectra of (1)-(111) are nearly superimposable it is likely that these highly reduced carbonyls are homologous.
