Study on the Methyl Migration of 10‐Methoxy‐5,10‐dihydrophenophosphazine 10‐oxide

Abstract

Ihe title compwnd (1) was treated with NaEIatmtempereture inanbydrous DMF to give a sodium salt (containing nitrogen anion) which could shift the methyl grlnlp from oxygen to nitrogen atom to form N-methyl phosphinic add IS tbe reaction temperature gatioa on the above reaction InedlMh which would be porsibly re-w a~ i n & to UO T. lhree nitro derivative^ containing 5,lO-dihydmphmphmphazine ring system were prepared for the inwstigarded IS a spedal inter-mdecular substitrdioa, *. , the nude-Ophiuenilrqp anion from one molecule d 1 a t t a d d the carbon atom of the 0-methyl of andher 1. In addition, the & e m i d shuctures of seven compolmds cootaining 5 , l c r d i h~ ptuizine ring system involved in the experhnt were contlrmed by IR, ' A m , "PNMRandmmspectroscopy.

Azaphosphinines and their derivatives

“…[42][43][44] Since then, the literature has been extremely sparse on publications concerning these chemicals. 45,46 Due to the wealth of previously compiled research and a dearth of recent studies, dihydrophenphosphazines will be excluded from the remainder of this review.…”
