NMR study (1H, 13C, 29Si, 31P and 119Sn) of the (C2H5)(3-n)PIVB(CH3)3 > n compounds (EIVB = C, Si, Sn; n = 0, 1, 2, 3)

1H, 13C, 29Si, 31P and 119Sn high-resolution NMR spectra of the series (C2H5)(3-n)PIVB(CH3)3 > n (EIVB = C, Si, Sn; n = 0, 1, 2, 3) have been studied at 90 and 300 Mc.The observed trend of chemical shifts and coupling constants are discussed in terms of inductive effects, through-space interactions and rehybridization of the phosphorus atom.Conclusive arguments in favor of d-orbital participation in the P-EIVB bonds were not found.
