New protocols for controlled reduction of carboxamides to either alcohols or amines were established using a combination of sodium hydride (NaH) and zinc halides (ZnX2). Use of a different halide on ZnX2 dictates the selectivity, wherein the NaH-ZnI2 system delivers alcohols and NaH-ZnCl2 gives amines. Extensive mechanistic studies by experimental and theoretical approaches imply that polymeric zinc hydride (ZnH2)∞ is responsible for alcohol formation, whereas dimeric zinc chloride hydride (H?Zn?Cl)2 is the key species for the production of amines.
A novel route to cyclopropyl ketones, aldehydes, and carboxylic acids
Rodriques, Karen E.
, p. 1275 - 1278 (2007/10/02)
Cyclopropanation of α,β-unsaturated N-methoxy-N-methyl amides provided the cyclopropyl amides in far superior yields to those obtained with the corresponding ketones. The desired ketones are then readily accessible by the addition of organometallic reagents. Access to a variety functional groups, including aldehydes and carboxylic acids, is also described.
NICKEL ENOLATES IN THE Ni(CO)4-INDUCED CARBONYLATION OF GEM-DIBROMOCYCLOPROPANES WITH SILYLAMINE OR SILYLSULFIDE

Silyl compounds (N,N-dialkyltrimethylsilylamine, 1-(trimethylsilyl)-imidazole and phenylthiotrimethylsilane) were successfully used in the Ni(CO)4-induced carbonylation reactions of gem-dibromocyclopropanes.The nickel carbenoid and enolate complexes are c
