Abstract
Background: 1, 1-Difluoroalkenes cannot only be used as valuable precursors for organic synthesis, but also act as bioisosteres for enzyme inhibitors. Among various methods for their preparation, the carbonyl olefination with difluoromethylene phosphonium ylide represents one of the most straightforward methods. Results: The combination of (chlorodifluoromethyl) trimethylsilane (TMSCF 2 Cl) and triphenylphosphine (PPh 3) can ...
