Chloro(triphenylmethyl)trisulfide (1) reacts under mild conditions with symmetric primary dialkyl disulfides and aromatic disulfides giving pentasulfides as the main products in good yield and selectivity. A mechanism involving a triphenylmethyl alkyl/phenyl tetrasulfide intermediate is discussed.

Triphenylthiosulfenyl chloride (1) reacts with disul®des RSSR, yielding tetrasul®des as the main products. The results of the insertion for dierent R groups are reported. A two-step mechanism involving the formation of unsymmetrical trisul®de intermediates containing the trityl group is proposed.
