Synthesis, physicochemical and optical characterization of novel fluorescing complex: O-phenylenediamine-benzoin

The complex of o-phenylenediamine (o-PDA) and benzoin (BN) was synthesized adopting solid state reaction by mixing of their melt together followed by chilling. The phase diagram study shows the formation of a complex in 1:1 molar ratio with congruent melt

Synthesis and investigation of mass spectra of some nitrogen heterocycles

2,3-DIPHENYL-1, 2-dihydro-quinoxaline (2), 2, 3-diphenyl-quinoxaline (3) and 2, 3-diphenyl-1, 2, 3, 4-tetrahydroquinoxaline (4) were prepared via the reaction of benzoin with o-phenylene diamine under different reaction conditions. Acylation of 2 and 4 with acetic anhydride yielded the corresponding N-acetyl (5) and N, N-1, 4-diacetyl derivative (7), respectively. Bromination of 2 with bromine gave the corresponding 6, 7-dibromo-2,3- diphenyl-quinoxaline (6). 2, 3, 5, 6-tetraphenylpyrazine (8) and 1-(benzylidene) amino-4, 5-diphenyl-1,5-dihydro-imidazoldine-2-thione (9) were synthesized by treatment of benzoin (1) with thiourea and benzaldehyde-thiosemicarbazone. The electron impact mass spectra of both of the above series of compounds have also been recorded and their fragmentation pattern is discussed.
