Abstract
We have demonstrated that
the flash pyrolysis of dipropargyl sulfide yields propynethial, HC≡CCHS,
among the products. The microwave spectrum of the major isotopic species of
propynethial and of HCCCH34S have been analysed. The derived
rotational constants for these species enable us to eliminate any alternative
structures for the pyrolysis product. The measured dipole moment components [μa
= 1.763(1) D; μb = 0.661(1); μtotal = 1.883(1)]
are discussed in terms of simple resonance structures.
