摘要：
Reaction of [Cr(eta(6)-C6H5Li)(2)].tmen with (RR')-NBCl2 (R = R' = SiMe3; R = R' = iPr; R = SiMe3, R' = tBu) and B2Br2(NMe2)(2), respectively, in hexane yielded the strained [1]borachromoarenophanes [Cr{(eta(6)- C6H5)(2)-BNRR'}] (4a-c; R = R' = SiMe3; R = R' = iPr; R = SiMe3, R' = tBu) and [2]borachromoarenophanes [Cr-{(eta(6)- C6H5)(2)(BNMe2)(2)}] (5), respectively, in moderate yields as dark red solids; compounds 4c and 5 were structurally characterized. 4c exhibits the largest arenearene tilt angle (26.6(3)degrees) reported for any [n]metal-loarenophane.
