Abstract

The reaction of β-fluoro vinamidinium salt 1 with Horner–Wadsworth–Emmons reagents (HWE) such as diethyl (ethoxycarbonyl) methylphosphonate (2a), diethyl (methoxycarbonyl) methylphosphonate (2b), diethyl-2-oxopropylphosphonate (2c), diethyl benzylphosphonate (2d), tetraethyl methylenediphosphonate (2e) and diethyl cyanomethylphosphonate (2f) under basic conditions gave the fluorinated 1, 3-butadienylphosphonates 3 in moderate to ...
