, p. 431 - 438 (1983)
The influence of the following factors on the solid-liquid PTC fluorination reaction of primary alkyl halides was studied: the catalyst quantity applied, the water content of solid alkali fluoride salt, and the type of catalyst.Kinetic curves at different temperatures were found for the reaction.The maximum yield is a function of the interaction of two parallel running reactions, namely the direct fluorination reaction and the catalyst decomposition.
Stereospecific Electrophilic Fluorination of Alkylcarbastannatrane Reagents

We report the use of isolable primary and secondary alkylcarbastannatrane nucleophiles in site-specific fluorination reactions. These reactions occur without the need for transition metal catalysis or in situ activation of the nucleophile. In the absence of the carbastannatrane backbone, alkyltin nucleophiles exhibit no activity towards fluorination. When enantioenriched alkylcarbastannatranes are employed, fluorination occurs predominately via a stereoinvertive mechanism to generate highly enantioenriched alkyl fluoride compounds. These conditions can also be extended to stereospecific chlorination, bromination, and iodination reactions.
Selective mono-acylation of 1,2- and 1,3-diols using (α,α- difluoroalkyl)amines

In the reaction of N,N-diethyl-α,α-difluorobenzylamine (DFBA) with 1,2- or 1,3-diols, selective mono-benzoylation occurs to afford mono-esters of the diols in good yield. The reaction is completed under mild conditions in a short reaction time. Further, prim-, sec-, and tert-diols and catechol can be converted to the corresponding mono-benzoates. DFBA is used for the protection of the hydroxy group in sugars. The selective mono-nicotinylation, formylation and pivaloylation of diols are also performed by using the corresponding difluoroalkylamines.
