Title	Ring-Opening Polymerization of Substituted 3,4-dihydro-2H-pyrans. Syntheses of Alternating Vinyl Copolymers of Dimethyl Dicyanofumarate and Electron-Rich Olefins
Author	Ju-Yeon Lee*, Iwhan Cho
Keywords
Abstract	Substituted 3,4-dihydro-2H-pyrans (1a-e) were prepared by (4 + 2) cycloaddition reaction of dimethyl dicyanofumarate with the corresponding electron-rich olefins. The compounds 1a-e were ring-open polymerized by cationic initiators to obtain polymers of 1:1 alternating sequence. Polymerizations were carried out with boron trifluoride etherate in methylene chloride at -78℃. All the polymers obtained were soluble in common solvents and were reprecipitated by pouring its chloroform solution into diethyl ether. All the compounds 1a-e were not as reactive as the corresponding pyrans derived from α -cyanoacrylate.
