Stereochemical effects in mass spectrometry: preferential formation of bromonium ions from trans-substituted 1,1′,2,2′-polyalkyl-2,2′-dibromodiethyl ethers
Abstract
The relative abundance of bromonium ions in the electron ionisation mass spectra of acyclic 1,1′,2,2′-polyalkyl-2,2′-dibromodiethyl ethers is enhanced by trans stereochemistry of the alkyl groups.
