Unlocking metal coordination of diborylamides through ring constraints
Brown, W. Kice,Klausmeyer, Kevin K.,Lindley, Brian M.
, p. 867 - 870 (2022/02/01)
A cyclic lithium diborylamide compound was synthesized and crystallographically characterized, revealing strong Li–N bonding in sharp contrast to previous linear diborylamides. Two iron(ii) diborylamide complexes were also synthesized, including a 2-coordinate Fe bis(diborylamide) complex. The present cyclic diborylamide represents a new addition to the growing scope of amide ligands.
Borylation of Arylsilanes, II. - Synthesis and Reactions of Silylated Dihalogenphenylboranes
Kaufmann, Dieter
, p. 901 - 906 (2007/10/02)
Upon treatment with trihaloboranes 4a and 4b the bissilylated benzenes 1, 2, and 3 yield the silylated dihalogenphenylboranes 5a-7b under substitution of one silyl group only.The corresponding difluoroboranes 5c-7c are easily accessible by a new fluorination method under mild reaction conditions by treating the dichloroboranes with lithium fluoride in ether.Upon heating with excess 4 the exchange of the second silyl group occurs, too, yielding the position-isomeric diborylbenzenes 9, 10, and 11.The bromination of the silylated dichlorophenylboranes 5a-7a proceeds with high regioselectivity under desilylation yielding 12, 13, and 14.The dimethoxyboranes 15, 16, and 17, synthesized by methanolysis of the corresponding dichloroboranes, can be coupled with bromobenzene under palladium(0) catalysis to yield the position-isomeric silylated biphenyls 18, 19, and 20.
