摘要:
The reaction of Cp2Ti(AsF6)2 (1) in liquid sulfur dioxide with XCN gave the cationic titanocene complexes [Cp2Ti(XCN)2][AsF6]2 (X = H, 2; D, 3). The bonding situation between the Lewis acid (Cp2Ti2+) and the Lewis base (XCN) is discussed on the basis of IR data and qualitative MO considerations. A convenient laboratory-scale synthesis of DCN is reported.
