Tetraethylammonium tetraselenotungstate: a new and efficient selenium transfer reagent for the chemoselective synthesis of functionalised diselenides
A variety of functionalised organodiselenides were prepared in excellent yields from the corresponding halides and activated alcohols on treatment with tetraethylammonium tetraselenotungstate 1 under very mild conditions

Utility of tetrathiomolybdate and tetraselenotungstate: efficient synthesis of cystine, selenocystine, and their higher homologues
Efficient synthesis of cystine, selenocystine, and their higher homologues like homo and bishomo amino acid derivatives from natural amino acid derivatives using tetrathiomolybdate and tetraselenotungstate reagents under mild and neutral conditions is reported. The generality of the reaction has been studied by capping various groups to amino and carboxyl components of canonical amino acids.

Synthesis and applications of propargyl pentafluorophenyl carbonate for peptide synthesis
Propargyl pentafluorophenyl carbonate was synthesised in quantitative yield by the reaction of propargyl chloroformate and pentafluorophenol. All the N-propargyloxycarbonyl (N-Poc) amino acids were obtained in good yield. The use of Poc-OPfp in peptide synthesis has been explored
