- Abstract: The first catalyst for the alkoxycarbonylation of gem ‐difluoroalkenes is described. This novel catalytic transformation proceeds in the presence of Pd(acac)2 /1, 2‐bis((di‐ tert ‐butylphosphan‐yl)methyl)benzene (btbpx) (L4 ) and allows for an efficient and straightforward access to a range of difluoromethylated esters in high yields and regioselectivities. The synthetic utility of the protocol is showcased in the practical synthesis of a Cyclandelate analogue using this methodology as the key step. Abstract : Die ersten selektiven Carbonylierungen von gem ‐Difluoralkenen wurden entwickelt, um einen allgemeinen Ansatz für eine Vielzahl von nützlichen difluormethylierten Estern in hoher Ausbeute und mit exzellenter Regioselektivität bereitzustellen.
