✦ Synopsis

The "P and "C NMR spectra of all twelve phenoxychlorocyclotriphosphazenes of general formula N3P3Cb-,(OC6H5), (n = 1-6) were assigned in detail. With samples abundant in one homolog, but with a disparity between geometrical isomers, the signals due to the cis and trans isomers of N3P3C14(OC6H5)2 and N3P3Cl2(0C6H,), were also assigned. The "P chemical shifts and coupling constants correlate linearly with the level of substitution, n. The 13C NMR spectra exhibit complex multiplets for the ipso-and ortho-carbons. It is shown that each of these is the X part of one of the spin systems XAM2, XAA'M, XAA,', XAB, and XAA'B. The 13C chemical shifts of the ipso-and pQrQ-CarbOnS also exhibit correlations with n. The 13C-3'P coupling constants, both 'J(P0C) and 3J(POCC), are larger for the PCl(OC6H5) than for the P(OC6H,), moieties.
