SULPHUR SUBSTITUTED ORGANOTIN COMPOUNDS. IX. FORMATION OF TRIPHENYLTIN, Ph3SnCH2CH2CHClCH2SC6H4NO2-o, FROM REACTION OF 4-BUTENYLTRIPHENYLTIN AND o-NITROBEZENESULPHENYL CHLORIDE

Reaction of the sulphenyl chloride, o-NO2C6H4SCl, with Ph3SnCH2CH=CH2 occurs to give the adduct, Ph3SnCH2CH2CHClCH2SC6H4NO2-o.In contrast, no adduct is formed with the more reactive, p-MeC6H4SCl.Instead, and as reported previously with Bu3SnCH2CH2CH=CH2, the cyclopropylmethyl aryl sulphide is obtained.The adduct is thermally stable, and reacts with I2 and HgCl2 to give phenyl-tin cleaved products, Ph2SnXCH2CH2CHClCH2SC6H4NO2-o (X=I or Cl).
