✦ Synopsis

The reactive molecule I-phosphapropyne, CHJt%P, which is the phosphorus analogue of methylcyanide CH&N, has been detected by microwave spectroscopy in the pyrolysis products of ethyldichlorophosphine CHaCHaPCla. The J = 3 +-2 and J = 4 + 3 sy_mme?ric top transitions have been assigned and a value of B o = 4991.339 f 0.010 MHz obtained. These results indicate that alkyl substituted analogues of phospha-acetylene, HC=-P can be produced by the pyrolysis of the appre priatcly substituted dichlorophosphine.
