Synthesis and Characterization of 3-Difluoroaminomethyl-3-methyl Oxetane and its Homopolymer

“…Affected by the unstable structures, difluoroamino compounds have not been practically use until 1980 th , while Chapman et al [2] found the similar cyclic structure with cyclotrimethylenetrinitramine (RDX) or cyclotetramethylenetetranitroamine (HMX) to keep difluoroamino group stable. This result opened the floodgate to some new kinds of difluoroamino compounds [3,4] and new routes for difluoroamino group introducing [5][6][7].…”

An Electrochemical Approach to Directed Fluorination

“…Moreover, ketones 8H and 10H successfully provide the predicted fluorinated congeners in 40% and 89% yields. These steroids give a good insight into the abilities of ketone-directed fluorination as each compound directs fluorination to distinct areas on the steroid, thus demonstrating a novel way to fluorinate 16 these potential bioactive sites in relatively good yields. 17 Furthermore, we offer preliminary data for heretofore unexplored imides 18 and lactams 19 operating as competent directing groups in at least a few cases.…”
