Titanocene-bis(trimethylsilyl)ethyne complexes [Ti(.eta.5-C5Me4R)2(.eta.2-Me3SiCđCSiMe3)], where R=benzyl, phenyl and p-fluorophenyl thermolyze at 150-160řC to give products of double C-H activation e.g. [Ti(.eta.5-C5Me4Ph){.eta.3:.eta.4-C5Me2Ph(CH2)2}]. In the presence of 2,2,7,7-tetramethylocta-3,5-diyne(TMOD), the thermolysis affords analogous doubly tucked-in-compounds bearing one .eta.3:.eta.4-allyldiene and one .eta.5-C5Me4R ligand having TMOD attached to two carbon atoms vicinal to substituent R.
