Synthesis and properties of the first crystalline 1,4-ylide, 9-cyano-10-methyl-10-thiaanthracene☆

Thioxanthyliumperchlorat (I) reagiert mit KCN zu einem Addukt (II), das in Gegenwart von Silbersalzen zu den Thioxanthylium-Salzen (III) substituiert wird.

A novel 1,4-cycloaddition reaction of a stable 2-thianaphthalene derivative: formation and X-ray crystal structure of 3-benzoyl-1a,2-dimethoxy-carbonyl-1-methylthio-1a,7b-dihydrocyclopropa[α]naphthalene

Treatment of 1-benzoyl-2-methyl-2-thianaphthalene (1a) with dimethyl acetylenedicarboxylate leads to a novel 1, 4-cycloaddition resulting in the formation of 3-benzoyl-1a, 2-dimethoxycarbonyl-1-methvlthio-1a,7b-dihydrocyclopropa [a]naphthalene (2) whose structure has been confirmed by X-ray crystallography.
