Abstract

Abstract: The stereospecific syntheses of cis-3, 4, 5, 6-tetrahydropyridazine-3, 4-dz (6) and cis-and trans-cyclobutane-l, 2-d2 are reported. The thermal decomposition of cis-3, 4, 5, 6- tetrahydropyridazine-3, 4-d2 (6)(gas phase, 439" C) affords 67.1 f 0.9% cis-ethylene-1, 2-d2, 16.1 f 0.8% trans-ethylene-1, 2-d2, 9.4 f 0.4% cis-cyclobutane-1, 2-dz, and 7.4 f 0.4% trans- cyclo-butane-1.2-dz. The relative rates of rotation, cleavage, and closure for this 1, 2- ...
