The role of the substituents in the chemistry of organoantimony(I) compounds

Abstract

Depending on the nature of the substituents organoantimony(I) compounds exist as polymeric chains, as cyclic compounds, dimeric or monomeric species. The influence of the substituent is discussed in this article.

Recent advances in the stabilization of monomeric stibinidene chalcogenides and stibine chalcogenides

“…[34][35][36][37] Beginning in the late 2000s, an extensive array of studies on the chemistry of pnictinidene chalcogenide compounds with aryl substituents bearing pendent donor groups were performed. [38][39][40] Dehydrocoupling following the reaction between L2SbCl 2 (L2 = C 6 H 3 -2,6-(CH 2 NMe 2 ) 2 ) and two equivalents of K[B(i-Bu) 3 H] afforded (L2Sb) 4 (Fig. 3d), 41 a tetrameric analog of (L1Sb) 2 in which the pendent N-donors of the L2 substituent interact with the Sb(I) centers.…”
