From the reaction of cinnamylideneacetophenone (1), sulfur and triethylamine in suitable solvents at room temperature, phenyl{3-[(E)-l-((5-benzoyl-3H-1,2-dithiol-3 -ylidene)phenylmethyldisulfanyl)-1-phenylmethylidene]-3H-1,2-dithiol-5-yl}methanone (7) was isolated together with two polysulfurated compounds to which structures of phenyl(7-phenyl-1,2,3-trithiepin-4-yl)methanone (12) and phenyl(8-phenyl-1,2,3,4-tetrathiocin-5-yl)methanone (13) were assigned. The obtaining of these new products allows to complete the sequence of the whole process.

Abstract
From the reaction of cinnamylideneacetophenone (1), sulfur and triethylamine in suitable solvents at room temperature, phenyl{3-[(E)-l-((5-benzoyl-3H-1,2-dithiol-3 -ylidene)phenylmethyldisulfanyl)-1-phenylmethylidene]-3H-1,2-dithiol-5-yl}methanone (7) was isolated together with two polysulfurated compounds to which structures of phenyl(7-phenyl-1,2,3-trithiepin-4-yl)methanone (12) and phenyl(8-phenyl-1,2,3,4-tetrathiocin-5-yl)methanone (13) were assigned. The obtaining of these new products allows to complete the sequence of the whole process.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
