Jj. Brunet et al., EASY PREPARATION OF COLLMAN-TYPE REAGENTS - REACTION OF [HFE(CO)(4)](-) WITH TRIS(DIMETHYLAMINO)PHOSPHINE, Synthetic communications, 27(8), 1997, pp. 1433-1437
The reaction of tris(dimethylamino)phosphine with MHFe(CO)(4) (M = Na,
K) is described. Instead of a CO-substitution at the Fe atom, a forma
l Me(2)N-substitution occurs at the P atom. Simultaneously, the Collma
n-type reagent M(2)Fe(CO)(4) is produced in good yield.
