Abstract

Abstract 2, 4-Dimethyl-3-phenyl-[2′-methyl-3′ chloro]-7-chloro-8-methyl-2, 4-dibora-1, 3- diazaronaphthalene (C 16 H 18 B 2 N 2 Cl 2) crystallizes in the monoclinic system: P 2/a; a= 8.149 (3) Å, b= 13.379 (3) Å and c= 15.193 (3) Å; β= 91.03 (2); Z= 4; R= 0.043; R w= 0.041. Reaction with [Cr (CO) 6] gives exclusively the compounds with Cr (CO) 3 η 6-bonded to the benzo part of the molecule. This derivative is a 1: 1 mixture of atropisomers which were ...
