Question
(LITERATURE) In 2013, Richard S. Givens, a professor at the University of Kansas, and several Czech friends of his published on a photo -catalyzed FAVORSKII Rearrangement. (a) in what journal did they published this? And (b) what two leaving groups were present on the ketones they used as reactants? (LITERATURE) The Reimer-Tiemann reaction is usually done on phenols or on highly activated benzene rings. In 2011, 3 Indian authors (Bhunia, Patra, and Pal) published an article claiming the Reimer-Tiemann could be made to work on a non -phenolic heterocyclic (coumarin) in strong base. (a) in what journal did they published this? (b) what carbon, or carbons, by numbered position on the coumarin ring received the attached formyl group? (c) what explanation did the authors offer as to why a non- phenolic starting material underwent the reaction?Explanation / Answer
1. a)Journal of Organic chemistry (J Org Chem.)
b) Br (Bromine) and OH (Hydroxyl)
2. a)SYNTHETIC COMMUNICATIONS
b)The Carbon numbered 6 (6th position on the coumarin ring) is formylated
c)Improved yields of aldehydes from the Reimer
