Abstract

Abstract The only detectable cobalt carbonyl species present in CoCRACO (NaH/t- AmONa/Co (OAc) 2/CO)(t-Am= tert-amyl) is NaCoCO 4. The simultaneous presence of NaH, t-AmONa, NaCoCO 4 and some soluble, non-carbonyl, cobalt species allows highly catalytic carbonylation of C 6 H 5 Br under very mild conditions, while NaCoCO 4 alone can carbonylate C 6 H 5 Br under irradiation (350 nm). In the presence of t-AmONa, the ...
