for the conversion of glycerol to allyl alcohol, where ammonia or organic acids are added to the feed as sacrificial reductants, was investigated. Significant enhancement on the rate of formation and yield of the allyl alcohol is observed with some of the reducing agents examined over an alumina-supported iron catalyst. Optimising the molar ratio of the reductant relative to feed glycerol results in an

Abstract The easily accessible 2-(chloroseleno)benzoyl chloride has broad application in the synthesis of benzizoselenazol-3(2H)-ones and benzo[b]selenophen-3(2H)-ones. Treatment of 2-acylbenzo[b]selenophen-3(2H)-ones with nitrogen nucleophiles such as hydrazines and hydroxylamine resulted in formation of 2-substituted 3-hydroxybenzo[b]selenophenes in 72–98% yield.

Reactions of 2-ferrocenylmethylidene-1,3-diketones () with methylhydrazine afford mainly insertion products (∼40–58%), viz., 1-(N′-acyl-N′-methylhydrazino)-1-ferrocenyl-2-acylethanes (), together with lesser amounts of pyrazoles () and dihydropyrazoles (). J. Heterocyclic Chem., 46, 484 (2009).
