标题 :Allyl esters substituted by a difluoromethylene group, their process of synthesis and their use, and a process for functionalizing a double bond
发明人：ROQUES NICOLAS
权利人:RHODIA CHIMIE SA
摘要:This invention provides compounds of formula: n n n in which R f is a radical that carries a perfluoromethylene group, which group ensures bonding to the remainder of the molecule; R1 and R3, which can be the same or different, are chosen from among hydrogen and alkyl or aryl radicals; Ψ is an electroattractor group such that Ψ-O—H is an acid whose pKa (in water) is at most equal to 8, advantageously 6, and preferably 5. These compounds are useful for the synthesis of nitrogen-containing heterocyclic compounds.

发明人：HEINRICH MARKUS; PRATSCH GERALD
权利人:UNIV FRIEDRICH ALEXANDER ER
摘要:The present invention describes a process for the synthesis of 2-aminobiphenyls and derivatives thereof. This method is inexpensive to carry out and based on selective implementation. Functionalized biphenyl compounds are of great interest in particular as pharmaceuticals and crop protection agents and as precursors of such active substances. The process for preparing a compound of formula 3 is characterized in that a compound of formula 1 is reacted with a compound of formula 2.
