Abstract
A new series of boron-nitrogen heterocyclics of general formula RR'N4BH were synthesized and their ultraviolet, infrared and Raman spectra studied (AD-632 448). Theoretical calculations on the 6-electron pi system were compared with experimental results. Proton n.m.r. spectra of the following selected compounds were obtained: Et20.GaC13, Et20.GaBr3, Et2S.GaC13 and Et2S.GaBr2. When analysed correctly these indicate that GaC13 is a stronger acceptor than GaBr3 towards these ligands and that Et2S is a better donor than Et20 towards the gallium trihalides. Interferrometric techniques have been used with considerable success to determine heavy metal- halogen and metal- ligand vibration and deformation frequencies. Coupled with Raman data this has allowed convincing assignments to be made of the spectra obtained on new compounds.
