Deuterioformylation of styrene catalyzed by [(2S,4S)-BDPP]Pt(SnCl 3)Cl at 39 °C gave 3-phenylpropanal (3) and 2-phenylpropanal (2) (n:i = 1.8, 71% ee (S)-2) with deuterium only β to the aldehyde carbonyl and in the formyl group. Small amounts o

A practical method for the one-step preparation of 3-arylpropionic acids through rhodium-catalyzed 1,4-addition of arylboronic acids to acrylic acid is reported. The method is applicable to a broad scope of aryl boronic acids and displays a wide functional group tolerance operating in water as the optimal reaction medium.

The rearrangement of 5-phenyl-1,1,1-trifluoro-2-(trifluoromethyl)pent-2-ene to 5-phenyl-1,1,1-trifluoro-2-(trifluoromethyl)pent-3-ene has been studied by 19F NMR in dimethylsulphoxide (DMSO). This isomerisation is catalysed by a base such as tr
COBALT-CATALYZED CARBONYLATION OF OPTICALLY ACTIVE AND α-DEUTERATED PHENETHYL HALIDES

Carbonylation of optically active α-phenethyl halides under phase transfer conditions gives hydratropic acid of the opposite absolute configuration.The inversion of configuration is accompanied by extensive racemization.The latter appears to originate from equilibria between keto and enol forms of acylcobalt-carbonyl complexes and between branched and linear alkyl complexes.Double carbonylation of α-phenethyl bromide is strongly inhibited when the benzylic hydrogen is replaced by deuterium.This large isotope effect provides the first experimental support for the proposed intermediacy of an enolic species in the double carbon monoxide insertion.
