NEIGHBOURING GROUP PARTICIPATION IN REACTIONS BETWEEN IODINE AND Ph3Sn(CH2)nS(O)mC6H4Me-p
Wardell, James L.,Wigzell, John McM.
, p. C24 - C26 (1981)
Reactions of Ph3Sn(CH2)nS(O)mC6H4Me-p (n = 2, 3 or 4; m = 0, 1 or 2) with iodine in CCl4 result in phenyl-tin bond cleavage.The relative reactivities indicate intramolecular nucleophilic catalysis by the sulphur-containing substituents.
