Page/Page column 7-8, (2008/06/13)
A process for hydrogenating a carboxylic acid and/or derivative thereof having a carboxylate group represented by the general formula R1COO-, which process comprises feeding hydrogen and the carboxylic acid and/or derivative thereof to a reactor and maintaining conditions within the reactor such that hydrogen reacts with the carboxylic acid and/or derivative thereof to produce a product stream comprising carbon dioxide, carbon monoxide, methane and hydrocarbons represented by general formulae R1H and R1CH3, characterised in that the molar ratio of R1H : R1CH3 is above a pre-determined value and/or the mole ratio of the sum of carbon dioxide, carbon monoxide and methane to carboxylate groups is above a pre-determined value.

gem-Dialkylation or alkylative reduction of α-unbranched aliphatic aldehydes 1 is advantageously achieved by reaction of the corresponding gem-bistriflates 2 with di-n-alkylcyanocuprates or di-sec- and di-tert-alkylcyanocuprates respectively. The reaction of α-branched gem-bistriflates 2 with dialkylcyanocuprates in the presence of boron trifluoride affords the olefins 6 in good yield.
Azo Anions in Synthesis: α-Amino Carbanion Equivalents from t-Butyldiphenylmethylhydrazones

α-Amino carbanion equivalents (=C(1-)NH2) and α-hydrazino anion equivalents (=C(1-)NHNH2) are readily accessible from the C-alkylation products of t-butyldiphenylmethylhydrazones; these azoalkanes can be efficiently transformed into amines, hydrazines, and also alkanes under mild reaction conditions.
AZO ANIONS IN SYNTHESIS. USE OF TRITYL- AND DIPHENYL-4-PYRIDYLMETHYLHYDRAZONES FOR REDUCTIVE C-C BOND FORMATION.

The lithium salts of trityl- and diphenyl-4-pyridylmethyl-hydrazones of both aldehydes and ketones react with electrophiles (alkyl halides, aldehydes, ketones, crotonates) at low temperature to form C-trapped azo compounds; these intermediates decompose homolytically with loss of nitrogen below room temperature and can be diverted in a synthetically useful way to alkanes, alkenes, alcohols or saturated esters.
