Preparation of polyfunctional arylmagnesium, arylzinc, and benzylic zinc reagents by using magnesium in the presence of LiCl

The presence of LiCl considerably facilitates the insertion of magnesium into various aromatic and heterocyclic bromides. Several functional groups, such as -OBoc, -OTs, -Cl, -F, -CF3, -OMe, -NMe2, and -N 2NR2, are well tolerated. The presence of a cyano group leads in some cases to competitive reduction of the organic halide to the corresponding ArH compound. The presence of sensitive groups such as methyl or ethyl ester is tolerated upon in situ trapping of the intermediate magnesium reagent with ZnCl2. This method can also be applied to the preparation of functionalized benzylic zinc reagents from benzylic chlorides. In the case of di- or tribromoaryl derivatives, directing groups such as -OPiv, -OTs, -N2NR2, or -OAc orient the zinc insertion (Zn/LiCl) to the ortho-position, while the reaction with Mg/LiCl or Mg/LiCl/ZnCl 2 leads to regioselective insertion into the para-carbon-bromine bond. Large-scale experiments (20-100 mmol) for all of the metalation procedures are described.

SYNTHESIS AND SPECTRAL STUDIES OF ALKYL-3- BENZOATES AND THEIR PHENYL SULFONYL DERIVATIVES

New methyl and ethyl-3- benzoates and their corresponding phenyl sulfonyl derivatives have been synthesized and identified by UV, IR and 1H-NMR.Both phenylthio 1 and 2 as well as phenyl sulfonyl derivatives 3 and 4 showed a linear relationship between chemical shift δ ppm of the benzylic protons and ?-Hammett constants. Key words: Arylthio; aryl sulfonyl benzoates, 1H-NMR.
