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.

Highly syn selective addition of aqueous HBr to hydrophobically shielded arylalkynes

Hydrophobically shielded alkynes HC≡C-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 H2C=C(-Br)-aryl (isolated yields 96%, no hydrolysis). Em
