Acyl chlorides RCOCl having bulky R substituents such as t-Bu and 2,4,6-tri-t-butylphenyl), react with pentacarbonylrhenate to give the acyl complexes RCORe(CO)5 which on heating give the acyl-bridged compounds.From molecular orbital calculations, Berke and Hoffmann have predicted that analogous complexes could be possible intermediated for methyl migration in CH3Mn(CO)5.The bimetallic complex with R=2,4,6-C6H2(CMe3)3 has been characterized by X-ray diffraction.A trimetallic triacyl complex is formed from 1,3,5-C6H3(COCl)3 and -.

Highly syn selective addition of aqueous HBr to hydrophobically shielded arylalkynes

Hydrophobically shielded alkynes HCC-aryl, carrying 2,6-di- and 2,4,6-tri-tert-butylphenyl as the aryl group, can add aqueous HBr on heating in moist chloroform solutions to produce pure H2CC(-Br)-aryl (isolated yields 96%, no hydrolysis). Employment of DCC-aryl furnished initially only the E stereoisomer of DHCC(-Br)-aryl (stereospecific syn addition), which was slowly both dedeuteriated and partially transformed to the Z stereoisomer by HBr. The strongly retarded HBr addition to H3C-CC-aryl in moist chloroform produced again more E than Z product, whereas a thermodynamic E/Z ratio of 10:87 was found in moist acetic acid. Substitution of Br by LiSnMe3produced H2CC(-SnMe3)-aryl with well resolved long range 119Sn NMR coupling constants.
