Assembly of unsymmetrical 1,3,5-triarylbenzenes via tandem reaction of β-arylethenesulfonyl fluorides and α-cyano-β-methylenones

, 2022
A transition-metal-free tandem reaction of β-arylethenesulfonyl fluorides and α-cyano-β-methylenones has been revealed. In the presence of cesium carbonate, 2-arylethenesulfonyl fluorides react with α-cyano-β-methylenones through a tandem Diels-Alder ...

Fluoride intake of infants living in non-fluoridated and fluoridated areas [PDF]

British Dental Journal, 2014
Data on fluoride exposure of infants are sparse. This study aimed to estimate total daily fluoride intake (TDFI) of infants aged 1-12 months, living in non-fluoridated and fluoridated areas in north-east England.Daily dietary fluoride intake was assessed using a three-day food diary coupled with analysis of fluoride content of food/drink consumed ...

Enantioselective Lewis Base Catalyzed Phosphonyldifluoromethylation of Allylic Fluorides Using C-Silyl Latent Pronucleophile

, 2020
The first enantioselective phosphonyldifluoromethylation is enabled by the use of diethyl (difluoro(trimethylsilyl)methyl)pho-sphonate reagent as a latent pronuclephile in Lewis base catalyzed substitution of allylic fluorides.
