L,3,2-Oxathiazolium-5-olat

In ahnlicher Weise iibertragt 4-Phenyl-l,3,2-oxathiazolium-5-olat das C,N,S-Strukturelement auch auf ein stabiles Alkylidin-phosphan15 und auf Benzo-cyclopropen1. ... [Pg.393]

Thiazol 5-(4-Brom-phenyl)-3,4-dimethoxycarbonyl- E8a, 722 (4-Ar— l,3,2-oxathiazolium-5-olat + ROOC — C = C — COOR)... [Pg.1106]

From Meso-ionic l,3,2>oxathiazolium-5>olates (Type B).— The photolysis (at 4045—4078 A) of the meso-ionic 4-phenyl-1,3,2-oxathiazolium-5-olate (1) yields, as the final products, benzonitrile, sulphur, and carbon dioxide. The suggested mechanism (1)- (2) (3) (4) receives experimental support from the fact that the ultimate intermediate (4) can be trapped (10%) as the substituted isothiazole (5) by means of dimethyl acetylenedicarboxylate, the alkyne undergoing 1,3-dipolar cycloaddition to the intermediate benzonitrile sulphide." ... [Pg.542]
