Abstract
The mass spectra of several pyrazaboles of type 1 where R and/or R′ = C2H5 have been studied. The loss of boron-bonded hydrocarbon moieties under electron impact is the predominant feature of all spectra. Some ultraviolet and nuclear magnetic resonance data on compounds of type 1 have been collected; bulky substituents were observed to lead to conformational isomers that can be detected by 13C NMR spectroscopyKeywords
