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.
期刊介绍:
Química Nova publishes in portuguese, spanish and english, original research articles, revisions, technical notes and articles about education in chemistry. All the manuscripts submitted to QN are evaluated by, at least, two reviewers (from Brazil and abroad) of recognized expertise in the field of chemistry involved in the manuscript. The Editorial Council can be eventually asked to review manuscripts. Editors are responsible for the final edition of QN.
