Abstract
The synthesis of unsymmetrical pincer ligands by reactions of diphenyl disulfide and diphenyl diselenide with bis(2-chloroethyl) ether in the system hydrazine hydrate–KOH was accompanied by the formation of 1,2-bis(phenylsulfanyl)ethane, 1,2-bis(phenylselanyl)ethane, and 1-(phenylselanyl)-2-(phenylsulfanyl)ethane as by-products with an overall yield of 23% as a result of nucleophilic cleavage of the C–O–C bond in the initial ether.
