Organometallic derivatives. Part I. Heteroannularly substituted trimethylsilylferrocenes
Abstract
1,1′-Bis(trimethylsilyl)ferrocene was prepared; one of its carbon–silicon bonds was cleaved with mercury(II) chloride to give (1′-trimethylsilylferrocenyl)mercury chloride. This ferrocenylmercury chloride reacted with copper(II) salts [CuX2(X = Cl, Br, SCN, or SO2Ph)] and iodine, to give the corresponding heteroannularly substituted trimethylsilylferrocenes, where X or iodine replaces the chloromercury group. It reacted also with sodium thiosulphate to give bis-(1′-trimethylsilylferrocenyl)mercury.
