Lamination inks have primarily been based on PVB or vinylic resins.
The Z and E isomers were not separated in all reactions; however, the Z/E ratio was obtained from the integration of the vinylic proton signal: the vinylic proton signal of the isomer Z appeared downfield from that of the isomer E.
In a landmark publication (Tetrahedron Lett., 1979, 3437) Professor Suzuki reported the discovery of a transition metal catalyzed cross coupling reaction between vinyl boronates and vinylic halides in the presence of base to give, regio- and stereoselectively, diene products.
