摘要
利用芳基锂与6,6-二烷基富烯发生加成反应,制得大取代环戊二烯基负离子。用六羰基钼配位,合成出13个钼—钼双核及5个钼—卤素单核羰基化合物.研究了其IR、~1H NMR、^(95)Mo NMR,测定了[(CH_3)_2C(m-CH_3C_6H_4)C_5H_4]Mo(CO)_3Br(1)的晶体结构.该晶体属于单斜晶系,晶胞参数为a=1.175(3),b=1.4196(2),c=1.1894(4)nm,β=118.03(2)°,V=1.75134 nm^3。Z=4,D_e=1.733g/cm^3,F(000)=904,μ=30.0cm^(-1),R=0.039,R_w=0.050,空间群为P2_1/α.
Thirteen molybdenum-molybdenum dimetallic and five molybdenum-halide cyclopentadienyl carbonyl compounds have been prepared from complexed hexacar bonylmolybdenum with bulkier substituted cyclopentadienyl anions which came from the reaction of 6, 6-dialkylfulvenes with aryllithium. Thier IR, ~1H. NME, ^(95)Mo NMR spectra have been dismissed. [(CH_3)_2 C(m-CH_3C_6H_4)C_5H_4] Mo(CO)_3 Br (1) has been determined by X-ray diffraction. The crystal is monoclinio, a=l.175(3), 6=1.4196 (2), c=1.1894(4)nm, β=118.03(2)°, V=1.75134 nm^3, Z=4,D_c=1.733g/cm^3, F(000)-904,μ=30.0cm^(-1), R_w=0.039, R_w=0.050, space group is P2_1/a.
