Abstract

13 14, 15 the first equivalent of lithium reagent. Disilyl compound 9 forms pale yellow crystals which can be stored indefinitely in the presence of air at room temperature. Since it is well established that silyl groups in arylsilanes are readily displaced by electrophiles,'disilyl compound 9 seemed to be an ideal stable substitute for the exceedingly reactive parent ITN in an electrophilic substitution study.
