In an environmentally benign solventless system, alcohols are rapidly oxidized to carbonyl compounds using hexamethylenetetramine-bromine on wet alumina under microwave irradiation.

Hexamethylenetetramine-bromine on wet alumina rapidly regenerates carbonyl compounds from their corresponding semicarbazone using microwave under solventless system.

Divalent metal (Mn, Co, Ni) complexes of the ligand hexamethylenetetramine (HMTA, C6H12N4) with sulfate, nitrate and fluoroborate as counter ions have been synthesized in ethanolic media. Whereas the complexes with BF4 and NO3 as counter ions have two molecules of hexamethylenetetramine, those with SO4 2as counter ion contain just one molecule of hexamethylenetetramine. The complexes have been ...
