Alkylidene complex of tungsten Me3Ge-CH{double bond, long}W(NAr)(OCMe2CF3)2 (1) (Ar = 2, 6 - Pr2i C6 H3) has been prepared by the reaction of Me3GeCH{double bond, long}CH2 with known alkylidene compound But-CH{double bond, long}Mo(NAr)(OCMe2CF3)2 at a molar ratio 1:1. Metallacycle [CH(GeMe3)CH(GeMe3)CH2]W(NAr)(OCMe2CF3)2 (2) was isolated from the same reaction when twofold excess of Me3GeCH{double bond, long}CH2 was used. The both compounds 1 and 2 were structurally characterized. They were found to have low activity in metathesis of 1-hexene and high activity in ROMP of cyclooctene and norbornene.
