1. Intermolecular Rearrangements The reaction between a cation and carbanion can result in more a less tight association. Therefore stereochemical changes in the carbon species will take place. Two conditions will arise: (a) with σ carbanions no doubt a tight structure R-M will be formed, but if the carbanion R– has a chiral centre, then due to loose form or R–(n), inversion of groups will take place and this will be detected by racemisation. – R + (b) ⊕ M RM with π carbanions geometrical isomerisation can take place either photo-chemically or thermally.
Huisgen first tried to classify cycloadditions according to the termini of one reaction partner, usually with longer chain. Thus Diels-Alder reaction is a 4 + 2 cycloaddition. + 32 MECHANISMS IN ADVANCED ORGANIC CHEMISTRY Similarly olefine dimerisation is a 2 + 2 cycloaddition. However this nomenclature is sometimes ambiguous. Classification based on the Number of Electrons The system generally adopted recognized the fundamental importance of the number of electrons involved in cycloaddition and classifies the reactions on this basis.
