Complexes, polymers tribromide

The general trend is to increase the selectivity of the addition. Selectivity is often increased by substituting pyridine-halogen charge transfer complexes or tribromides of organic bases for the free halogens. Instead of pyridine an insoluble polymer can be applied. Although the rate of reaction is lower compared to the almost instantaneous reaction of free bromine, this technique facilitates isolation and purification of the product. ... 

According to the second mechanism the polymer and antimony trioxide form a catalytic complex. The halogen flame retardant then reacts with the complex and expels antimony tribromide.

Lanthanum dibenzyl complexes with triazanonane-silylamide, amidine and 1,3-diketiminate monoanionic ancillary ligands were also prepared by in situ peralkylation in the presence of the protonated ligand or by com-plexation (for 1,3-diketiminate) with lanthanum tribromide and subsequent alkylation. The coordination polymer [p-r 2 r 1-ArNC(Me)CHC(CH2)-NAr]2La[K(THF)4] n formed by H-abstraction from one of the diketimi-nate Me groups and a ligand redistribution.14...

Recently, we explored haloboration polymerization between boron tribromide and terminal diynes to give poly(organoboron halide)s as a polymeric Lewis acid, which has scarcely ever been known [13]. These poly(organoboron halide)s were also prepared by means of hydro-boration polymerization between dienes and monobromoborane as shown in Scheme 4 [14]. As a typical example, 1,7-octadiene was added to a 1.0 M dichloromethane solution of monobromoborane-dimethyl sulfide complex with stirring at 0°C under nitrogen. The molecular weight of the polymer obtained was increased when the feed ratio of monobromoborane to diene approached or slightly exceeded unity.
