X-ray diffraction study. The structure consists of isolated molecules in which a Cr(CO)5 fragment of approximate C4v symmetry is bonded via sulphur to the thioacylferrocene with an CrS bond length of 2.412(1) Å, an SC bond length of 1.667(2) Å and a C-S-Cr angle of 121.9(1)°. Photo oxidation of (C5H5)Fe[C5H4CPhSM(CO)5}] yields benzoylferrocene the crystal structure of which was determined.
Acylferrocenes(C 5 H ^ 5)的Fe(C 5 H ^ 4 COR)(RCH 3,C 2 H ^ 5,(CH 3)2 CH,(CH 3)3 C或PH)可以容易地thionated得到thioacylferrocenes由在非极性溶剂(如CH 2 Cl 2或
甲苯)中使用P 4 S 10;使用极性溶剂(例如THF或
二甘醇二
甲醚)的转化率非常低。
