The palladium-catalyzed coupling reaction of arylboronicacids with ethyl glyoxylate provides a straightforward method for the synthesis of mandelic esters. Pd2(dba)3·CHCl3 in combination with 2-di-tert-butylphosphanylbiphenyl as the catalytic system and Cs2CO3 as the base were used. The reaction tolerates a wide range of functionalized boronicacids. Mandelic esters were isolated in good-to-excellent

The present invention relates to trifluoromethyloxadiazoles of the formula I, or the N-oxides, or the agriculturally useful salts thereof, and to the use thereof for controlling phytopathogenic fungi; to a method for combating phytopathogenic harmful fungi, which process comprises treating the fungi, the plants, the soil or seeds to be protected against fungal attack, with an effective amount of at least one compound of the formula I, or an N-oxide, or an agriculturally acceptable salt thereof; and to agrochemical compositions comprising at least one compound of the formula I, or an N-oxide, or an agriculturally acceptable salt thereof; and to agrochemical compositions further comprising seeds.
A copper-catalyzed reaction of a-azidocarbonyl compounds under an oxygen atmosphere is reported where nitriles are formed via C C bond cleavage of a transient Iminyl copper intermediate. The transformation is carried out by a sequence of denitrogenative formation of iminyl copper species from alpha-azidocarbonyl compounds and their C C bond cleavage, where molecular oxygen (1 atm) is a prerequisite to achieve the catalytic process and one of the oxygen atoms of O-2 was found to be incorporated Into the beta-carbon fragment as a carboxylic acid.
