Pd-Catalyzed Nucleophilic Fluorination of Aryl Bromides
On the basis of mechanism-driven reaction design, a Pd-catalyzed nucleophilic fluorination of aryl bromides and iodides has been developed. The method exhibits a broad substrate scope, especially with respect to nitrogen-containing heteroaryl bromides, and proceeds with minimal formation of the corresponding reduction products. A facilitated ligand modification process was shown to be critical ...
متن کاملComplexes of triphenylphosphine oxide with lanthanide bromides
The reaction between hydrated lanthanide bromides and triphenylphosphine oxide in 1:3 and 1:4 ratios in ethanol gave a series of complexes [LnBr2(Ph3PO)4]Br (Ln = Pr, Nd, Gd, Tb, Er, Yb, Lu) which contain ethanol and water in the lattice, regardless of the ratio of reactants used. The single crystal x-ray structures of [NdBr2(Ph3PO)4]Br, [GdBr2(Ph3PO)4]Br and [YbBr2(Ph3PO)4]Br have been determi...
متن کاملEfficient synthesis of functionalized organozinc compounds by the direct insertion of zinc into organic iodides and bromides.
Significance: Organozinc compounds are very useful intermediates in synthesis of complex organic molecules due to their high reactivity combined with an excellent tolerance of functional groups. So far, the direct insertion of commercial zinc dust into organic halides was limited only to alkyl iodides and tertiary bromides, which diminished its synthetic value. Herein, a new method, allowing th...
متن کاملThe Elimination of Bromides from the Blood
Two dogs, weighing 15 and 20 kilos respectively, were employed for the experiments. Bromide in blood and urine was determined by the method of Behr, Palmer, and Clarke (1) ; total halide was estimated in aliquot portions of the alkaline ash solutions by the Harvey modification of the Volhard procedure (2). Carbon dioxide was estimated in serum (collected under oil) by the procedure of Van Slyke...
