1,2,3,5-Tetrazinones and zwitterionic 1,2,4-triazolin-3-ones
Autor: Ahmet E. Baydar, Gerhard V. Boyd, Peter F. Lindly, Adrial R. Walton
Publikováno v: Journal of the Chemical Society, Chemical Communications. :225
Treatment of 2-arylazo-1,1-dimethylguanidines (1) with phosgene yields the novel 1,2,3,5-tetrazinones (2), together with isomeric dipolar triazolinones (4); both types of product decompose to give nitrogen, dimethylcyanamide, and aryl isocyanate.

The chemistry of azides derived from N-substituted phthalamic and tetrahalogenophthalamic acids
Autor: Gerhard V. Boyd, Ahmet E. Baydar, Ting Keung Au
Publikováno v: Journal of the Chemical Society, Perkin Transactions 1. :2884
Treatment of eight phthalisoimidium perchlorates with sodium azide gave N-substituted o-carbamoylbenzoyl azides (2), which yielded o-carbamoylphenyl isocyanates (4) when heated. The isocyanates derived from tertiary phthalamic acids formed 4-dialkyl

Action of N-phenylmaleimide and 1-diethylaminopropyne on a 1,3-oxazin-2-one
Autor: Frank Watson, Gerhard V. Boyd, Peter F. Lindley, Ahmet E. Baydar
Publikováno v: Journal of the Chemical Society, Chemical Communications. :178
Whereas N-phenylmaleimide and 6-morpholino-5-phenyl-1,3-oxazin-2-one (1) yield the pyridine derivative (3) by a Diels–Alder reaction, the action of 1-diethylaminopropyne on the oxazinone results in the isomeric adducts (5) and (9), which are though

Isoimidium salts derived from diphenylmethylenesuccinic acid and their conjugate bases. Ene-type reactions involving transfer of acyl groups
Autor: Ahmet E. Baydar, Gerhard V. Boyd
Publikováno v: Journal of the Chemical Society, Perkin Transactions 1. :1360
The amic acids (2a–d), obtained from diphenylmethylenesuccinic anhydride and amines, were converted into the isoimidium perchlorates (4a–d). Deprotonation of the ternary salts yielded the isolable butenolides (5a–c), which formed ene-type adduc

Publikováno v: Journal of the Chemical Society, Chemical Communications. :650
The unsaturated lactones, 3-morpholino-1H-2-benzopyran-1-one (6), 2,3-dihydro-5-morpholinofuran-2-one (19a), and its 3-(diphenylmethylene)- derivative (19b) add to numerous compounds containing electrondeficient multiple bonds to give products arisin

Approaches to 1,2,3,5-tetrazines. Synthesis of 1,2,3,5-tetrazinones and the formation of zwitterionic 1,2,4-triazolin-3-ones and 1-arylimino-1,2,4-triazolium salts

Publikováno v: Journal of the Chemical Society, Perkin Transactions 1. :415
The reaction of phosgene with 1,1 -dialkyl-2-arylazoguanidines (3) yields 4-dialkylamino-1-aryl-1,2,3,5-tetrazin-6-ones (5), together with traces of zwitterionic 5-dialkylamino-1-arylimino-1,2,4-triazolin-3-ones(7); both decompose when heated to give

Synthesis of 2H-1,3-oxazin-2-ones
Autor: Gerhard V. Boyd, Ahmet E. Baydar
Publikováno v: Journal of the Chemical Society, Chemical Communications. :718
Treatment of C-substituted ternary maleisoimidium perchlorates (5), (18), and (24) with sodium azide gave the corresponding maleamic acid azides, which on heating underwent a Curtius rearrangement, followed by electrocyclisation, to yield 6-dialkylam
