Effect of iminic nitrogen substituents on [4+2] versus [3+2] cycloaddition pathways in reactions of nitrosoalkenes with simple acyclic imines: an experimental and theoretical investigation

An indepth experimental and theoretical investigation has been carried out so as to explore the effect of iminic nitrogen substituents in influencing the [4+2] versus [3+2] cycloaddition pathways followed in their reactions with nitrosoalkenes.
