Approaches to the study of the geometry and mechanism of nucleophilic reactions at sulfur(II)
… the required reaction trajectory and geometry of nucleophilic attack at two different sulfur(II) species is reported. Systems designed to investigate the reaction trajectory involving nucleophilic attack at sulfur(II) by use of the endocyclic restriction test are discussed.

A Study of the Chemistry of Thietan-3-Ones and Related Substances
… attempted using pyridine or triethylamine. The nucleophilic reactions of the chlorothietanones have been studied using pyrrolidine, morpholine, piperidine, methanol, benzylmercaptan and hydrazine derivatives. The hydrazine derivatives have been shown to attack both the C-2 and C-3 carbon of the …

I. Multicatalysis: Development of a BiOTf₃-catalyzed Nucleophilic Addition/Hydrofunctionalization Reaction in the Synthesis of Complex Heterocycles; . . .
… was part of a multicatalytic strategy combining nucleophilic additions to aliphatic aldehydes and N-tosyl imines to quickly generate complex 5-membered heterocycles in moderate to good diastereoselectivity. The palladium-pivalate catalytic system has emerged as one of the most efficient and …
