Reactions of dimethyltitanocene with alkynes and nitriles

Group 4 metallocene complexes with pendant nitrile groups

“…Motivated by known intermolecular reactions of the unsubstituted dimethyltitanocene with nitriles under thermal conditions [11], we made attempts to perform a controlled thermolysis of 10 in toluene-d 8 at 80 C. Unfortunately, an intractable mixture of products was observed by the NMR spectroscopy. However, methane could be identified as one of the products, indicating the expected route of thermolysis starting with CH 4 elimination.…”

“…Thermolysis of Cp 2 TiMe 2 (3) at 80 °C in benzene (7 -9 h) in the presence of internal alkynes 27 forms the corresponding titanacyclobutenes 28 cleanly and efficiently (Scheme 8) [11].…”
