The effect of trimethylsilyl substituents on the ring-slippage of bis-indenyl-molybdenocene derivatives

摘要: Abstract A group of new trimethylsilyl indenyl derivatives molybdenum is reported, starting from the allyl compound TMSIndMo(η3-C3H5)(CO)2 [TMSInd=η3-SiMe3C9H6]. The novel Mo(II) complex, which synthesized by reaction Mo(η3-C3H5)(CO)2(NCMe)2Cl with Li(TMSInd) in THF, precursor to derivatives. Treatment HCl and addition LiInd or LiTMSInd gives ring-slipped complexes (η5-TMSInd)Mo(η3-Ind)(CO)2 (η5-TMSInd)Mo(η3-TMSInd)(CO)2 high yield. presence substituent changes substantially flexibility groups. These substituted were characterized experimental techniques ab initio calculations, examined cyclic voltammetry.
