✦ Synopsis
In the previous letter we reported the effect of substituents on the rate of 154s + ,,2s3 reactions of the cyclobutene (I) with 3,6_di(2*pyridyl)-8-tetrazine (II), a diene having inverse electron demand. Whereas the g-methoxycompound [Ia] reacts faster than the unsubstituted compound (Ib) by a factor of
