摘要:
Reaction of Hf*Cl-2 (1; Hf* = decamethylhafnocene), with excess sodium acetylide at room temperature results in the synthesis of Hf*(CCH)(2) (2). The identical reaction in refluxing THF results in the dimeric product [(mu(2)-C-2)(Hf*CCH)(2)] (4). Subsequent reaction of 2 with lithium diisopropylamide (LDA) in the presence of trimethyltin chloride resulted in the trimetallic Hf*(CCSnMe(3))(2) (3).
