A Convenient and General Synthetic Method for Photochromic Fulgides by Palladium-Catalyzed Carbonylation of 2-Butyne-1,4-Diols
摘要:
Palladium-catalyzed carbonylation of substituted 2-butyne-1,4-diols affords a variety of photochromic fulgides in one step. This methodology provides an alternative to the traditional method based on the Stobbe condensation.
