This book provides a comprehensive and up-to-date compilation of the chemistry and applications of phosphorus ylides in organic synthesis. The ylides are discussed as reagents in the synthesis of a broad range of substances, amongst them olefins, acetylenes, cyclic and heterocyclic compounds, in such naturally occurring compounds as pheromones, steroids and carotenoids, and pharmaceutically and biologically active compounds such as antibiotics and p 606 $aYlides 606 $aOrganophosphorus compounds 606 $aOrganophosphorus compounds$xSynthesis 615 0$aYlides. 615 0$aOrganophosphorus compounds. 615 0$aOrganophosphorus compounds$xSynthesis. 676 $a547.05 676 $a547.07 676 $a547.070459 700 $aKolodiazhnyi$b Oleg I.$0542845 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a996201943103316 996 $aPhosphorus ylides$92230624 997 $aUNISA
