2 。实验
All manipulations were carried out under nitrogen stan-
dard Schlenk techniques. Solvents were purified by stan-
dard procedures and distilled under nitrogen prior to use.
NMR spectra were recorded with a Bruker AMX 300 spec-
trometer. Infrared spectra were recorded with a Unicam
Mattson Model 7000 FTIR spectrophotometer using KBr
pellets. Elemental analyses were performed in our laborato-
ries (ITQB). Standard literature methods were utilized for
the preparation of [MoO2Cl2] [8], the 1,3-dialkyl-4,5-dim-
ethylimidazol-2-ylidenes were readily available by the
reduction of the corresponding imidazol-2(3H)-thiones
with potassium in boiling THF [9], while the 1,3-dibutyl-
4,5-dichloroimidazol-2-ylidene was obtained by deprotona-
tion of the corresponding imidazolium salts bytBuOK [10].

A solution of 1,3,4,5-tetramethylimidazol-2-ylidene
(0.74 g, 6.00 mmol) in THF (20 cm3) cooled to 20 °C,
was added to a suspension of MoO2Cl2(0.60 g, 3.00 mmol)
in THF (30 cm3) at 20 °C and the reaction mixture was
stirred for 1 h at low temperature. The product,
MoO2Cl2(LMe)2(1), immediately precipitated as a purple
powder directly from the reaction mixture, and was iso-
lated by filtration and washed twice with cold THF to yield
pure solid of 1 (1.14 g, 85%). Anal. Calc. for C14H24Cl2-
