Abstract

-HNR2 t demonstrated the capability of substituted 1, 2, 4-triazines to react with electron-rich olefin^,^ though subject to dubious regio~ ontrol,~ for the preparation of substituted (3)(a) For an excellent treatment of the chemistry of 1, 2, 4-triazine derivatives see: Neunhoeffer, H.; Wiley, PF Chem.
