- W1969896502 abstract "The reaction of aniline hydrochloride with POCl3has been shown to yield the trimeric cyclophosphazane (PhNPOCl)3in good yield and purity, in opposition to the earlier results of Michaelis which assigned a dimeric structure to the product. The trimeric nature has been confirmed by 31P n.m.r. spectroscopy, mass spectroscopy, and an X-ray crystallographic structure determination. The analogous 4-methylphenyl and 4-methoxyphenyl compounds have been similarly prepared. The products are relatively inert to nucleophiles but reactions with ethoxide and hydroxide ions yield products which give evidence for a mechanism involving ring contraction by transannular attack of nitrogen on phosphorus." @default.
