The N-alkylation of phenylacetamide with benzyl alcohol has been studied using Ni/SiO2–Al2O3. In the optimized conditions, the desired product was isolated in an excellent 98 % yield. The reaction could advantageously be performed in neat conditions, with a slight excess of amide and a catalytic amount of base. These conditions were tested on a large range of amides and alcohols, affording 24 compounds in 13 to 99 % isolated yields.
One-Carbon Homologation of Primary Alcohols to Carboxylic Acids, Esters, and Amides via Mitsunobu Reactions with MAC Reagents

A method is reported for the one-carbon homologation of an alcohol to the extended carboxylic acid, ester, or amide. The process involves the Mitsunobu reaction with an alkoxymalononitrile, followed by unmasking in the presence of a suitable nucleophile. The homologation and unmasking can even be performed in a one-pot process in high yield.
Carboxyl activation of 3-mercapto-5,6-diphenyl-1,2,4-triazine through N-phenylacetyl-5,6-diphenyl-1,2,4-triazine-3-thione

The carboxyl activation ability of 3-mercapto-5,6-diphenyl-1,2,4-triazine has been established by coverting it into N-phenylacetyl-5,6-diphenyl-1,2,4-triazine-3-thione and this was then subjected to aminolysis and esterification with amines and alcohols respectively and selective aminolysis with aminoalcohols-monitoring chemically and confirmed spectrophotometrically by UV-Visible scannings. It could be proved that 3- mercapto-5,6-diphenyl-1,2,4-triazine is an efficient carboxyl activating group which can be successfully applied in solid phase peptide synthesis.
