Nucleophilic reactivities of tributylstannyl-substituted furans and thiophenes.
Kinetic investigations of the reactions of benzhydryl cations with stannylated furans and thiophenes suggest that 2-(tributylstannyl)furan and -thiophene are preferentially attacked at the 5-position (k(rel), FcPhCH(+), 20 degrees C, CH(2)Cl(2)).
