Phosphine–borane derivatives. Part IV. The proton nuclear magnetic resonance and vibrational spectra of some alkylphosphine–boranes

Abstract

The ¹H n.m.r. spectra of MePH₂BH₃, Me₂PHBH₃,EtPH₂BH₃, and Et₂PHBH₃ confirm that all are monomeric adducts, while those of MePH₂BD₃, Me₂PHBD₃, EtPH₂BD₃, and Et₂PHBD₃ confirm that there is no proton–deuteron exchange. The i.r. and Raman spectra are reported and features are discussed.
