マイクロ波照射によるホスホニウム塩の反応　

抄録

Microwave-assisted halogenation of hydroxyheteroaromatics and dehydration of primary amides were accomplished using phosphonium salt prepared by reaction of triphenylphosphine and N-chloro compounds. N-Chlorosuccinimide (NCS) and trichloroisocyanuric acid (TCICA) were used as a N-chloro compound. Both halogenation of hydroxyheteroaromatics and dehydration of primary amides under microwave-assisted condition proceeded without solvent in a short reaction time, whereas completion of the same reaction under thermal condition required solvent and longer time.
