  摘要：

  Re[C(O)Ar'](CO)5 (Ar' = 2,4,6-C6H2Me3; 1) can be prepared in 55% yield by adding ArC(O)Cl to [Re(CO)5]-. Addition of trifluoromethanesulfonic anhydride to 1 in dichloromethane yields off-white [Re(CAr')(CO)4(OTf)](OTf) (2) quantitatively. Three equivalents of tetraethylammonium chloride reacts with 2 in dichloromethane to give [Et4N[Re(CAr)(CO)2Cl3] (3), which when treated with TlBF4 in the presence of pyridine affords lemon yellow Re(CAr')(CO)2Cl2(py)(4). A slurry of 2 in dichloromethane also reacts cleanly with a THF solution of LiO-2,6-C6H3-i-Pr2 (LiOAr) to yield blood red Re(CAr')(CO)2(OAr)2(THF) (5a) in 80% isolated yield. Addition of pyridine to 5a yields an analogous six-coordinate pyridine adduct (5b). Addition of pinacol to 2 followed by triethylamine yields yellow, pentane-soluble Re(CAr')(CO)2(O2C2Me4) (6a). Although 6a shows no tendency to bind THF, it reacts with pyridine to yield Re(CAr')(CO)2(O2C2Me4)(py) (6b) quantitatively. Addition of triphenylphosphine to 6a produces dark red Re(CAr')(CO)(O2C2Me4)(PPh3) (6c).

The structures of trans-[Re(CR)(pdpp)2Cl]ClO4·CHCl3·0.25MeOH and [Re(CR)(PPh3)2(CO)(H2O)Cl]ClO4·1.5MeOH have been determined by X-ray analyses.
