REACTIVITY OF SULFUR(II) COMPOUNDS. CHEMICAL PROPERTIES AND FRONTIER MOLECULAR ORBITAL ANALYSIS

Abstract

Some aspects of the reactivity of sulfur(II) compounds—specially of N,N'-thiobisamines, toward hydrolysis, alcoholysis. and formation of coordination compounds—are discussed using experimental and theoretical results. Frontier molecular oribitals obtained from CNDO/2 calculations including sulfur d orbitals for a set of representative sulfur(II) species show that the reactivities of these compounds. following the series:

[Me₂NSNHMe²]⁺ > S(OH)₂ > SCl₂ > neutral thiobisamines > thiobisphthalimide. are adequately described by considering both charge and orbital effects.

Key Words:
