Synthesis and reactivity of silylated tetrathiafulvalenes

10.1039/b803947j

The research focuses on the synthesis and reactivity of novel organosilylated tetrathiafulvalenes (TTFs) with Si–H or Si–Si bonds. The study involves the preparation of various silylated TTF derivatives using reactions with chlorosilanes and lithium diisopropylamide (LDA) to introduce SiMe2H and Si2Me5 groups. Key chemicals used include TTF, chlorodimethylsilane, chlorodiphenylsilane, pentamethylchlorodisilane, and [Ru3(CO)12] for the synthesis of metal complexes. The researchers also attempted to convert Si–H bonds to Si–O functions using water and tris(dibenzylideneacetone)dipalladium(0), but observed cleavage of the CTTF–Si bond instead. The study explores the electrochemical properties of these compounds through cyclic voltammetry and investigates the electronic structure using DFT calculations. The reactivity of the Si–H bond is exploited to prepare dinuclear complexes with ruthenium, such as [{Ru(CO)4}2{l-(Me2Si)4TTF}] (14), and further transformations with phosphine ligands like PPh3 and dppm. The research aims to develop new silylated TTFs with potential applications in organometallic chemistry and materials science.
