SYNTHESES OF KINETICALLY UNSTABLE NEUTRAL FORMYL COMPLEXES VIA LI(C2H5)3BH AND TRANSFORMYLATION REACTIONS OF METAL-CARBONYL CATIONS

abstract

• Low-temperature syntheses of the kinetically unstable formyls (-C5H5)Re(NO)(CO)(CHO) (9), (C5H5)Mn(NO)(CO)(CHO) (10), Re(PPh3)(CO)4(CHO) (11), Mn(PPh3)2(CO)3(CHO) (12), Ir(PPh3)2(CO)2(CHO) (13), and (-C5H5)Mo(PPh3)(CO)2(CHO) (14) by reaction of Li(C2H5)3BH with the corresponding metal carbonyl cations are described. Formyls 9, 10, and 11 can also be synthesized by hydride transfer from the stable neutral formyl (-C5H5)Re(NO)(PPh3)(CHO) (1) to the appropriate metal carbonyl cation precursor (transformylation); this procedure avoids formation of byproduct (C2H5)3B. Whereas 9 (in dilute solution) and 13 decarbonylate to detectable metal hydrides upon warming, the decomposition chemistry of the other formyls is more complex and sometimes involves the dichloromethane cosolvent. 1982, American Chemical Society.
