Abstract
Abstract Isomerically pure 3-methyl-1-phenyl-2-phospholene 1-oxide and 3-methyl-1-phenyl-3-phospholene 1-oxide were prepared and characterized by 1H (60 and 270 MHz), 31P and 13C nmr, IR, Laser Raman, and mass spectrometry. 1,4-Cycloaddition of isoprene and phenylphosphonous dichloride, after hydrolysis of the addition product, yielded a mixture of the above 2-isomer and small amounts of 3-isomer from which pure 2-isomer was separated by fractional crystallization. The analog reaction with phenylphosphonous dibromide gave isomerically pure 3-isomer. An improved and shortened work-up procedure for the phospholene oxides was used resulting in higher yields.
