Abstract
A series of novel, cyclic, volatile, N-alkylgallazanes (RNHGaH2)n(R = Et, Prn, Pri, Bun, Bui, Bus, or But), has been synthesised and characterised by analyses, molecular weight determinations, and i.r., 1H n.m.r., and mass spectroscopic measurements. The effect of R group on ring size and conformational properties has been investigated. Normal alkyl groups lead to trimeric gallazanes whereas with branched-chained alkyl groups a preference for a dimeric structure has been demonstrated. Isopropyl gallazane and s-butyl gallazane are mobile liquids at room temperature and novel 1H n.m.r. and i.r. spectra have been obtained on the neat liquids.Keywords
