Bis(neopentyloxy)triphenylphosphorane: A Versatile, Nonalkylating Cyclodehydration Reagent
Bis(neopentyloxy)triphenylphosphorane (BNTP; 31P delta -58.3) is prepared in 48percent yield by reaction of 2 equiv of lithium neopentoxide with dibromotriphenylphosphorane in anhydrous dichloromethane from -78 to 25 deg C.BNTP smoothly converts a variety of diols, 2-aminoethanol, and 4-mercaptobutanol to the corresponding heterocycles in excellent yields (>95percent) by 13C and 31P NMR analysis.
