REACTION OF DICHLOROTETRACARBONYLDIRHODIUM, RH2CL2(CO)4, WITH TERT-BUTYL ISOCYANIDE

By studying the evolution of CO from Rh2Cl2(Co)4 in various solvents with successive additions of t-BuNC and by measuring the conductances and infrared spectra of these solutions, the course of the reaction and the nature of the intermediates have been established. The intermediates RhCl(CO)2(t-BuNC) and RhCl(CO)(t-BuNC)2 in the formation of [Rh(t-BuNC)4]Cl were isolated as blue-black solids from yellow solutions. © 1979.
