The dehydration of phosphinylated ketones led to formation of fluorinated phosphinylated enones, which can be used as versatile applicable building blocks in organic chemistry.Recently, there has been considerable interest in the derivatives of hydroxybisphosphonates because of their biological properties and medical application. Herein we presented a first attempt to synthesize a new class of fluorinated bisphosphinates. Unfortunately, these products are sensitive to moisture and undergo the phosphinate-phosphonate rearrangement quickly.deinfo:eu-repo/semantics/openAccessphosphinatesfluorinated diketonesphosphinylated aminesfluorinated phosphinylated enonestrifluormethylpyruvatediastereomeric mixtureX-rayHPLCregioselectivity540Dissertationurn:nbn:de:gbv:46-diss000112385
