Abstract

AbsbPct Second-order rate constants for the reactions of para-substituted diarylmrbenium ions (ArAr 'CH'= 1) with allylsilanes 2, allylgermanes 3, and allylstannanes 4 have been determined in CH2C12 solution at-70 to-30 OC. Generally, the attack of ArAr'CH+ at the CC double bond of the allylelement compounds 2-4 is rate-determining and leads to the formation of the j3-element-stabilized carbenium ions 5, which subsequently react with the ...
