Reaction of [Cr(η 6 -C 6 H 5 Li) 2 ]‚tmen with (RR′)-NBCl 2 (R ) R′ ) SiMe 3 ; R ) R′ ) iPr; R ) SiMe 3 , R′ ) tBu) and B 2 Br 2 (NMe 2 ) 2 , respectively, in hexane yielded the strained [1]borachromoarenophanes [Cr{(η 6 -C 6 H 5 ) 2 -BNRR′}] (4a-c; R ) R′ ) SiMe 3 ; R ) R′ ) iPr; R ) SiMe 3 , R′ ) tBu) and [2]borachromoarenophanes [Cr-{(η 6 -C 6 H 5 ) 2 (BNMe 2 ) 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)°) reported for any [n]metalloarenophane.
