摘要:
Cp-2 degrees ZrCl2 (Cp degrees = eta(5)-C5EtMe4) reacts with LiPHCy (Cy = cyclohexyl) with the formation of Cp-2 degrees ZrCl(PHCy) (1). Compound 1 undergoes insertion of CS2 or PhNCS into the Zr-P bond, yielding Cp-2 degrees ZrCl(eta(2)-S2CPHCy) (2) and Cp-2 degrees ZrCl{eta(2)-SC(PHCY)NPh} (3). Compounds 1-3 were characterized spectroscopically (IR, NMR, MS) and crystal structure determinations were carried out on 1 and 3, showing an eta(2)-bonding mode of the SC(PHCy)NPh (S, N) ligand in the latter.
