✦ Synopsis

‫ס‬ hexamethylenimino; and 11 ‫ס‬ anilino] afford the phosphiniminocyclotrithiazene derivatives, 12-22 at room temperature. Only in the case of the phosphine 10 was the disubstituted derivative 23 isolated (in 65% yield). The trithiazene derivatives of the chiral phosphines in refluxing CH 3 CN produce the acyclic compounds →PN-S 3 N, 24-27 in ca. 60% yield. Norbornadiene reacts at room temperature with the cyclotrithiazene derivatives to give the addition products 28-35. →P‫ס‬N-S 3 N 3 derivatives are found to be stable

Dibenzocycloheptenylidene (2,4,6-tri-t-butylphenyl)phosphine and fluorenylidene(2,4,6-tri-t-butylphenyl)phosphine were prepared by the reactions of lithium silylphosphide with benzosuberenone and fluorenone, respectively. The reactions of the phosphines with sulfur were carried out to compare the re
