Focusing primarily on the literature that has appeared since 1984, Padwa (chemistry, Emory U.) and Pearson (chemistry, U. of Michigan) present 12 contributions that survey applications of [3+2]-cycloadditions in organic synthesis. The chapters cover nitrones, nitronates, azomethine ylides, carbonyl ylides, thiocarbonyl ylides, nitrile oxides, nitrile ylides and nitrile imines, diazoalkanes, azides, mesoionic ring systems, effect of external reagents, and asymmetric reactions
