Abstract
Trialkylsilyl lithium species have turned out to be facilely generated by treating hexaalkyl disilanes with methyl lithium in the presence of tris( N,N -tetramethylene)phosphoric triamide (TPPA) as an activator, which can be trapped by boron electrophiles to afford silylboronic esters including long-awaited Me 3 Si–B(pin).
