Reactions of 9,10-Dihydro-9,10-dimethyl-9,10-diboraanthracene (1) with the isolobal 14 VE metal complex fragments Ru(CO)3, Co(C5H5), Fe(C7H8) and Ni(C8H12) yield the 18 VE compounds 2, 3, 4 and 5. With (CO)3Cr(CH3CN)3 complexation takes place at the carbacyclic moiety of 1 to give 6. Neither reduction nor carbonylation of 6 at 40 bar CO pressure result in a slippage of the chromium carbonyl group towards
9,10-二氢-9,10-二甲基-9,10-二硼蒽蒽(1)与等规14 VE金属络合物片段Ru(CO)3,Co(C 5 H 5),Fe(C 7 H 8)的反应)和Ni(C 8 H 12)生成18个VE化合物2、3、4和5。与(CO)3 Cr(CH 3 CN)3的络合发生在1的碳环部分,得到6。6既不还原也不羰基化在40 bar CO压力下,羰基铬基向1的杂环部分滑移。的反应3与(CO)3的Cr(CH 3 CN)3个通向34 VE“滑”三重双层7。络合物2、3和4可逆地还原,得到顺磁性的19 VE单阴离子。的电化学2,3和4的以及ESR数据3 -和4 -报告。的构造2,3,4和5已经通过X-射线结构分析证实。
