Abstract

Vinylic Substitution of 10-(Halomet hy lene)-anthrones. The (halomethy1ene) anthrones 3 and 4 reacted with nucleophiles, yielding the corresponding a-substituted 10- methyleneanthrones 5 and 6 or their subsequent products, as shown in Table I and Scheme 11. Treatment of 3a, b with sodium azide in N, N-dimethylformamide (DMF) gave 10- (azidomethy1ene) anthrone (tis), whose structure was substantiated by the infrared ...
