By copolymerising with a small amount of second monomer which acts as an obstruction to the unzipping reaction, in the event of this being allowed to start. On the industrial scale methyl methacrylate is sometimes copolymerised with a small amount of ethyl acrylate, and formaldehyde copolymerised with ethylene oxide or 1,3-dioxolane for this very reason. [Pg.97]

Jaacks and his colleagues [17] have claimed that when they terminated dioxolan polymerisations with sodium ethylate, they could detect ethyl ethers. It seems to us that these results may very well be due to the same kind of impurity and/or side-reaction that gave us the involatile phenylether, and therefore this evidence alone cannot at present be taken as proof of their mechanism. [Pg.734]

A mixture of 5-phenyl-l,3-dioxolane-2,4-dione (63a) (178 mg, 1.0 mmol) and 4 A MS (100 mg) in anhydrous Et O (50 mL) was stirred at room temperature for 15 min, then cooled to -78 °C, after which (DHQD)jAQN (95%, 90.2 mg, 0.1 mmol) was added to the mixture. The resulting mixture was stirred for a further 5 min and then EtOH (1.5 eq) was added dropwise over 10 min by syringe. The resulting reaction mixture was stirred at -78 °C for 24 h. HCl (IN, 5.0 mL) was added to the reaction dropwise and the resulting mixture was allowed to warm to room temperature. The organic phase was collected, washed with aqueous HCl (IN, 2 x 5.0 mL) and the aqueous phase was extracted with Et O (2 x 5.0 mL). The combined organic extracts were washed with brine, dried (Na SO ) and concentrated in vacuo. Purification by EC on silica gel (EtOAc/hexanes, 1/4) gave (R)-ethyl mandalate (64a) as a white solid (128 mg, 71%, 95% ee by chiral-HPLC). [Pg.271]
