Transmetallation is also appropriate for creating boron-nitrogen bonds. Starting from molecules containing (acidic) NH functions, the nitrogen atom is readily metallated by n-butyl lithium. Subsequent reaction of the lithium amide with a suitable element halide provides the desired precursor, while the lithium halide is eliminated (Eq. 5) [25, 27] ... [Pg.143]

A new, general method of preparation of isocyanates has been reported, in which carbamate esters are treated with BCI3 in the presence of EtjN in refluxing benzene solution. The mechanism of the reaction (Scheme 16) involves the formation of a transient intermediate containing a boron-nitrogen bond from which BCblOR ) is eliminated. ... [Pg.70]

Detailed investigations are being conducted in the field of boron-nitrogen polymers with N— B coordinative bonds due to their hydrolytic stability (superior to that of the polymers containing tricoordinate boron). Such plastics and elastomers are likely to become candidates for special applications because of the high cross-section of 10B for the (n, a) reaction.171... [Pg.101]
