Palladium-catalyzed cross-coupling of cyclopropylmagnesium bromide with aryl bromides mediated by zinc halide additives.
J. Org. Chem. 75(19) , 6677-80, (2010) The key Pd-catalyzed cross-coupling of aryl bromides or triflates and cyclopropylmagnesium bromide in the presence of substoichiometric amounts of zinc bromide produces cyclopropyl arenes in good to excellent yields. The cross-coupling of other alkyl, cycloal... |

Stereoselective glycosylations using benzoylated glucosyl halides with inexpensive promoters.
Carbohydr. Res. 343(8) , 1297-308, (2008) Reactions of O-benzoylated glucopyranosyl halide (I, Br), isolated or generated in situ from per-benzoylated glucose (8a) and trimethylsilyl halide, with various alcohols were efficiently promoted by zinc halide (Cl, Br) or N-bromosuccinimide with a catalytic... |

[Halogenated anesthetic vaporizers: importance of maintenance regulations].
Ann. Fr. Anesth. Reanim. 17(7) , 747-9, (1998) We report a serious dysfunction of 19 halothane vaporisers Vapor 19.3 (Dräger) which delivered a much higher concentration of agent than indicated on the dial. This inaccuracy was linked to a major corrosion of the inner layers of the vaporiser, with a deposi... |

alpha,alpha-gem-Difluorination of alpha-(alkylthio)acetophenone derivatives with N-fluoropyridinium salts.
Chem. Pharm. Bull. 48(7) , 1097-100, (2000) The alpha,alpha-gem-difluorination of 2',4'-difluoro-alpha-(methylthio)acetophenone (1a) with N-fluoropyridinium salts gave 2',4',alpha,alpha-tetrafluoro-alpha-(methylthio)acetophenone (3a). This reaction was accelerated by the addition of zinc chloride, zinc... |

Silyl protecting groups for oligonucleotide synthesis removed by a ZnBr2 treatment.
Nucleosides Nucleotides Nucleic Acids 24(5-7) , 1009-13, (2005) An oligonucleotide protected with N-(trimethylsilyloxycarbonyl) (Teoc) and P-(trimethylsilylethanol) (Tse) groups was synthesized and deprotected by a single ZnBr2 treatment. Finally it was released from the solid support by cleavage of a disulfide linkage wi... |

Nicotine aerosol generation from thermally reversible zinc halide complexes using the Staccato system.
Drug Dev. Ind. Pharm. 34(9) , 936-42, (2008) Application of the Staccato system to liquid drugs presents unique technological challenges. Liquids, such as nicotine, do not form physically stable films on vaporization substrates. We identified two thermally reversible zinc halides (ZnCl2 and ZnBr2) that ... |
