Hydrodefluorination of functionalized fluoroaromatics with triethylphosphine: A theoretical and experimental study

Recently we reported the metal free hydrodefluorination of selected fluoroaromatics using triethylphosphine as the sole defluorinating agent. That prompted us to evaluate the mechanistic proposal and in the light of these results, along with new experimental evidence, we have now modified the initial proposal. The new mechanism avoids the highly energetic β-elimination step of roughly 71 kcal mol-1 for hexafluorobenzene and pentafluoropyridine at 393.15 K, invoking the participation of water. The use of D2O confirmed the role of water as the hydrogen source, yielding the corresponding deutero-defluorinated products; DFT calculations agree with this new proposed mechanism. We also report herein the use of this one-pot hydrodefluorination method applied to a broader number of fluoroaromatic derivatives; some of them allowed the collection of key mechanistic evidence.

Antimycotically active substituted 2-aminothiazoles

Antimicotically active 2-aminothiazoles have been found having the formula STR1 in which R1 represents hydrogen or alkyl and R2 represents optionally substituted cyclohexyl or phenyl which is substituted by halogen, alkyl, halogenoalkyl, halogenoalkoxy, dioxyhalogenoalkyl or halogenoalkylthio, and their physiologically tolerable acid addition salts, with the exception of the compounds 4-(4-chlorophenyl)-2-[2-(1,4,5,6-tetrahydropyrimidinyl)-amino]thiazole and 4-(2,4-dichlorophenyl)-2-[2-(1,4,5,6-tetrahydropyrimidinyl)-amino]-thiazole and 4-(4-chloro-2-methylphenyl)-2-[2-(1,4,5,6-tetrahydropyrimidinyl)-amino]-thiazole and with the exception of the physiologically tolerable acid addition salts of these compounds have been found.
