Kinetics and Mechanism of Desulfination

The only kinetic study was that conducted on the reaction shown in Eq. (19) 88) where the isolated product is sometimes the dinuclear 

REACTIONS OF SULFUR DIOXIDE WITH o-ALLYL, PROPARGYL, CYCLOPROPYL, AND CYCLOPROPYLMETHYL COMPLEXES OF TRANSITION METALS 

Three classes of transition metal-carbon cr-bonded compounds exhibit a behavior toward SO2 which is different from that discussed in Section III. They are (1) allyl, (2) propargyl, and (3) cyclopropyl and cyclo-propylmethyl complexes. Their reactions with SO2 will be considered in this same order. 

Two general types of 5-sulfinate have been isolated from reactions of metal-cT-allyl complexes with SO2 (1) that derived from insertion of SO2 into the original M—C bond [Eq. (20)] and (2) that resulting from 

Several generalizations are possible from these data.
