Expression of dipolar character in diyl trapping chemistry

A set of new reactions is described and illustrated in eqs 1-5. Diazenes which customarily participate in diradical processes, compounds 1a and 9 for example, lead to intermediates which are intercepted by water. Diazene 3 is converted to an intermediate which is intercepted both by water and, when the dielectric constant of the medium is sufficiently high, by n-PrOH
