Interaction of xylylisocyanide with CrVI(Nmesityl)2(SC6F5)2
摘要:
The interaction of 2,6-dimethylphenylisocyanide (xylNC) with Cr(Nmes)(2)(SC6F5)(2) in refluxing toluene gives mer-Cr(SC6F5)(3)(xylNC)(3) 1 and minor amounts of trans-Cr(SC6F5)(2)(xylNC)(4) 2. Compound 2 is best made by interaction of either Cr(mes)(2)(THF)(3) or CrCl2 with C6F5SH or C6F5SNa, respectively, in the presence of xylNC. The X-ray crystal structures of 1 and 2 have been determined. The similar imido thiolates of molybdenum(VI) are inert towards xylNC. (C) 1997 Published by Elsevier Science Ltd.
