(115-C5HS) 2ZrC6H5 [CD (Sc6H5)(Si (cH3) 3)] show this rearrangement to be intramolecular. Activation parameters for the rearrangement of (115-C5H5) ZZrC6HS [CH (sc6H5)(Si (CH3) 3)] were found to be AH*= 20.30 (43) kcal/mol and AS*=-19.0 (2) eu. It is proposed that this rearrangement proceeds by intramolecular nucleophilic attack (migration) of the aryl group to the methylene carbon with commensurate breaking of the CS bond. A ...
