摘要

烯烃与硫原子亲电加成的最新进展。有机氧原化合物(含S, Se和Te)从生物学的角度来看是很有趣的,而且它们还可以作为获得复杂分子的中间体,甚至用于探索它们的性质。这样,亲电试剂硫是非常强的反应物,可以加入到烯烃中形成一个三元中间体,叫做硫鎓离子。这个物种与不同的亲核试剂反应,产生一系列具有有趣性质的含硫原分子。从硫原到烯烃的亲电试剂的加成是这些化合物化学领域中最古老的反应之一,因此已经探索了许多修饰。其中,利用过渡金属的方法到最近探索绿色化学方面的方法。本文首先介绍了烯烃中有机产醇化合物的亲电加成反应的研究背景,然后介绍了近年来合成有用分子的方法,希望能对该领域的进一步研究和思考有所帮助。

RECENTES AVANÇOS NA ADIÇÃO ELETROFÍLICA DE ORGANOCALCOGÊNIOS A ALQUENOS
RECENT ADVANCES IN THE ELECTROPHILIC ADDITION OF CHALCOGEN ATOMS TO ALKENES. Organochalcogen compounds (containing S, Se and Te) are interesting from biological point of view, but also in their use as intermediates in obtaining complex molecules or even for exploring their properties. In this way, chalcogen electrophiles are very powerful reactants and can be added to alkenes to form a three-membered intermediate called chalcogeniranium ion. This specie reacts with different nucleophiles to undergo a series of molecules containing chalcogens with interesting properties. The addition of electrophiles from chalcogens to alkenes is one of the oldest reactions in the field of the chemistry of these compounds and because of this many modifications have already been explored. Among them, methodologies that make use of transition metals to the most recent ones exploring aspects of Green Chemistry. This review starts with an overview of the background involved in electrophilic addition reactions of organochalcogenic compounds in alkenes and then, describes the recent methodologies leading to the synthesis of useful molecules and hoping that it will be beneficial to provoke further research and reflection in this field.
