1,2-Distannylation and -disilylation of cyclic allenes
Abstract
Cyclo-1,2-dienes(C9–C13) are converted into the synthetically promissing 2,3-bis(trimethylsilyl)- and 2,3-bis(trimethylstannyl)cycloalk-1-enes by disilylation with lithium chlorotrimethylsilane in tetrahydrofuran, and Pd0-catalysed addition of hexaalkyldistannes, respectively.
