Abstract
1,4-Bis(acylsilanes) were prepared by substitution of 1,2-bis(triflates) wi th 2-lithio-2-trimethylsilyl-1,3-dithiane or by silylation of 1,2-bis([1,3] dithian-2-yl)ethane and dethioketalization with methyl iodide or mercuric s alts. The reaction with 1,2-dihalogenated alkanes gave dehydrodimers of 2-t rialkylsilyl-1,3-dithianes. The cyclodehydration of the 1,4-bis(trialkylsil yl)-1,4-butanediones gave 2,5-bis(trialkylsilyl) furanes. (C) 2000 Elsevier Science Ltd. All rights reserved.
