R2 = C6H5 (1c); R1 = H, R2 = 4-CH3C6H4 (1d); R1 = H, R2 = 4-OMeC6H4 (1e); R1 = H, R2 = 4-ClC6H4 (1f); R1 = H, R2 = 4-CF3C6H4 (1g)). Complexes 1a−1g were characterized by NMR spectroscopy, elemental analyses and FT-IR spectroscopy. Furthermore, the molecular structures of complexes 1a, 1d and 1g were determined by single crystal X-ray diffraction analysis. In the presence of TEMPO (2,2,6,6-tetramethyl-1-piperidinyloxyl)
用吡啶醇盐配体PyC(CH 2)4 OH(L a H)和PyCR 1 R 2 OH(R 1 = CH 3,R 2 = C 6 H 5(L b H )热处理Re 2(CO)10); R 1 = H,R 2 = C 6 H 5(L c H); R 1 = H,R 2 = 4-CH 3 C 6 H 4(L dH); R 1 = H,R 2 = 4-OMeC 6 H 4(L e H);R 1 = H,R 2 = 4-ClC 6 H 4(L f H);R 1 = H,R 2 = 4-CF 3 C 6 H 4(L g H))分别在回流的二甲苯中生成一系列的羰基dir配合物[PyC(CH 2)4 O] 2 [Re(CO)3 ] 2(1a)和(PyCR 1R 2 O)2 [Re(CO)3 ] 2(R 1 = CH 3,R 2 = C 6 H 5(1b); R 1 = H,R 2
