Abstract

Abstract: An understanding has been obtained of the complex mechanisms that are followed when alkyl or aryl Grignard reagents react with (NPCI,),(2) in tetrahydrofuran. The main products are monoalkylcyclotriphosphazenes (3) and bi-(cyclotriphosphazenes)(4). The predominance of one product or the other depends on the reaction temperature and on the organic functionality of the Grignard reagent. The structural characterization of the bi ( ...
