Competitive [4+2] cycloadditions in equimolar mixtures of 1-arylphosphole oxides

Four different [4+2] cycloadditions were observed to take place in the equimolar mixtures of two different arylphosphole oxides 2a + 2b or 2b + 2c. In addition to the phosphole oxide dimers 3a-a and 3b-b, or 3b-b and 3c-c, the crossed cycloadducts 3a-b and 3b-a, or 3b-c and 3c-b were also formed in considerable portions.

Preparation and synthetic uses of a 2-lithiophosphole

1-Phenyl-2-bromo-3,4-dimethylphosphole was prepared from 1-phenyl-3,4-dimethylphosphole via a sequence involving oxidation at phosphorus, bromination and dehydrobromination of the dienic system, and finally, PV to PIII conversion by
