Reactivite des dienes et styrenes fluores obtenus par reaction de couplage au palladium

Fluorodienes and fluorostyrenes undergo clean cycloaddition to form perfluorocyclobutanes.Fluorostyrenes have been prepared by a palladium-catalyzed cross-coupling reaction.Treatment of fluorodienes under acidic conditions gives various α-fluorocarbonyl c

The spin-delocalization substituent parameter σ JJ?. Part 10. The spin-delocalizing abilities of the para-trifluorovinyl and para-acetoxy groups. Synthesis of para-trifluorovinyl-, para-vinyl-and para-acetoxy-α,β,β-trifluorostyrenes

para-Trifluorovinyl α,β,β-trifluorostyrene (1-CF=CF2), p-acetoxy α,β,β-trifluorostyrene (1-AcO) and p-vinyl α,β,β-trifluorostyrene (1-CH=CH2) have been synthesized. The rate constants (k) for the thermal cyclodimerization of 1-CF=CF2 and 1-AcO have been measured over the temperature range 90-130 °C for 1-CF=CF2 and 110-160 °C for 1-AcO. The σmb polar substituent constants of the p-CF=CF2, p-CH=CH2 and p-AcO groups calculated from the 19F NMR chemical shifts are: for p-CF=CF2, 0.40; for p-CH=CH2, 0.03; and for p-AcO, -0.14, and the σ JJ? spin-delocalization substituent constants of the p-CF=CF2 and p-AcO groups are 0.86 and 0.35, respectively, i.e., the former is a highly effective spin-stabilizer while the latter is moderately effective. Owing to the occurrence of a small amount of side-reaction, the σ JJ? value of the p-CH=CH2 group could not be accurately measured, but it was very roughly estimated to be in the range of 0.50-0.66.

PREPARATION METHOD FOR FLUORINE-CONTAINING OLEFINS HAVING ORGANIC-GROUP SUBSTITUENTS

An object of the present invention is to provide a method that enables the easy and efficient (high yield, high selectivity, low cost) preparation of a fluorine-containing olefin substituted with an organic group or groups from a fluorine-containing olefin. [Solution] The method for preparing a fluorine-containing olefin substituted with an organic group or groups, the method comprising a step of reacting a fluorine-containing olefin with an organic boron compound in the presence of an organic transition metal catalyst containing at least one transition metal selected from the group consisting of nickel, palladium, platinum, rhodium, ruthenium, and cobalt.

Room temperature preparation of trifluoroethenylzinc reagent by metalation of the readily available halocarbon HFC-134a and an efficient, economically viable synthesis of 1,2,2-trifluorostyrenes

Trifluoroethenylzinc reagent [CF2=CFZnX] was generated from the readily available halocarbon HFC-134a by an in situ metalation-transmetalation procedure at temperatures near to room temperature (15-20 °C). By systematic standardization of the m

Palladium - Catalyzed Cross - Coupling of Perfluoroalkenylzinc Reagents with Aryl Iodides. A New, Simple Synthesis of α,β,β-Trifluorostyrenes and the Stereoselective Preparation of 1-Arylperfluoroprepanes

Perfluoroalkenylzinc reagents coupled with aryl iodides in the presence of Pd(PPh3)4 (1-3 molpercent) to give the corresponding arylalkenes.A series of substituted α,β,β-trifluorostyrenes were prepared in good yields.This method provides ready availability of these fluorinated styrenes, which were previously obtained with difficulty.For the first time, 1-arylperfluoropropenes were prepared stereoselectively.Palladium-catalyzed reactions of 2 with aryl iodides gave stereospecific (E)-1-arylperfluoropropenes, and the same procedure with 3 gave stereoselective Z/E ratios ranging from 98/2 to 92/8.
