Abstract:
Comparative studies on the reactivity of a transiently formed terminal phosphinidene complex towards various organobromide derivatives show that carbon-bromine bond insertion is preferred with benzyl bromide, whereas formal HBr-insertion resulted with 2-bromopyridine and a surprising selectivity enhancement (of the phosphinidene complex) was observed with bromobenzene; all new products were established by elemental analyses, NMR spectroscopy, mass spectrometry and single crystal X-ray diffraction studies.

Electrophilic Addition to Alkynes: Halogenation
Halogenation is another class of electrophilic addition reactions where a halogen molecule gets added across a π bond. In alkynes, the presence of two π bonds allows for the addition of two equivalents of halogens (bromine or chlorine). The addition of the first halogen molecule forms a trans-dihaloalkene as the major product and the cis isomer as the minor product. Subsequent addition of the second equivalent yields the tetrahalide.
