摘要:
A new derivative of tbe carboxyl group, N-methyl-2-alkylimidazoline, was introduced with the aim of improving the control of fatty acid fragmentation. Owing to the strongly basic character and the cyclic structure of this derivative, strong stabilization of the charge on the ionized group is obtained so that extensive radical and charge-remote fragmentation of the chain can be achieved with electron impact and electrospray ionization.
