Synthesis and Structural characterization of syn and anti η~6 9,10 Dihydro 9,10 ethenoanthracene 11 carboxylic methyl ester) tricarbonylchromium

9,10 -二氢 - 9,10 -乙烯基蒽 - 11-甲酸甲酯 (1)与 Cr(CO) 6在正丁醚溶液中反应 ,分别得到顺式和反式 (η6- 9,10 -二氢 - 9,10 -乙烯基蒽 - 11-甲酸甲酯 )三羰基合铬 (2和 3) ,其中顺式异构体 2的结构已由

The bent biarene, 9,10 Dihydro 9,10 ethenoanthracene 11 carboxylic methyl ester ([ST5HZ]1), reacts with hexacarbonylchromium in bibutyl ether to give both syn and anti (η 6 9,10 dihydro 9,10 ethenoanthracene 11 carboxylic methyl ester) tricarbonylchromiumtriene([ST5HZ]2 and 3), of which the structure of the syn isomer ([ST5HZ]2) is unequivocally determined by single crystal X ray analysis.
