TLDR
In this article, Diazomethane reacts with organoditellurides, diselenides, and disulfides to give telluro-, seleno-, and thioacetals.Abstract:
Die Umsetzung von Diazomethan mit einigen Ditelluriden, Diseleniden und Disulfiden ergibt die entsprechenden Tellur-, Selen - und Thioacetale. Mechanismen fur diese Umsetzungen werden vorgeschlagen.
Reaction of some Ditellurides, Diselenides, and Disulfides with Diazomethane
Diazomethane reacts with organoditellurides, -diselenides, and -disulfides to give telluro-, seleno-, and thioacetals. Mechanisms for this reaction are suggested.read more

Free Radicals and Free‐Radical Reactions of Monovalent and Divalent Sulfur
TL;DR: In this paper, it was shown that the Steric hindrance and resonance stabilization, which are responsible for the stability of the triarylmethyl, diphenylnitrogen, and phenoxyl radicals, are insufficient to stabilize the organic free radicals of monovalent sulfur in such concentrations that they can be detected by current physical methods.
