The reaction of 3-hydroxymethyIpyridine 1-oxide with methyl fluorosulfonate and potassium cyanide provides a direct method for 2,6-dicyanation (75JOC2092). However, the generality of this method is limited by the need for a 3-substituent that can form an anhydrobase. In this example (Scheme 138) the anhydrobase is formed by methylation of the 3-hydroxymethyl group followed by elimination either during or subsequent to attack by the second mole of cyanide. The use of such a powerful methylating agent overcomes... [Pg.261]

Diglycidyl ether of bisphenol-A (DGEBA), epoxy resin (YD 128, Kuk Do Chem., Mn = 378), and bisphenol-A dicyanate (BPACY, Arocy B-10, Ciba-Geigy) were used as the thermoset resin. 4,4 -diaminodiphenyl sulfone (DDS, Aldrich Chem. Co.) was used as a curing agent for epoxy. Polyetherimide (PEI, Ultem 1000, General Electric Co., M = 18,000) and 2-methyl imidazole (2MZ, Aldrich Chem. Co.) were used as the thermoplastic modifier and catalyst. [Pg.117]
