Organic syntheses consists of protocols for the synthesis of useful chemical compounds. Organic Syntheses, Volume 87 provides carefully checked and edited experimental protocols that describe important synthetic methods, transformations, reagents, and synthetic building blocks or intermediates with demonstrated utility in organic synthesis. For each protocol, safety warnings are presented along with detailed experimental descriptions for the preparation, purification, and identification of the compound. Additionally, special reaction conditions are also detailed. This current volume continues the tradition of providing significant and interesting procedures for synthetic chemists working in increasingly diverse areas.
