An efficient protocol for the synthesis of brominated norbornene, norbornadiene, and benzonorbornadiene

An efficient protocol for the synthesis of 2-bromonorbornene, 2-bromonorbornadiene, 2-bromoben- zonor-bornadiene, 2,3-dibromonorbornene, 2,3-dibromonorbornadiene, and 2,3-dibromobenzonorbornadiene in good yields has been developed. 1,2-Dibromotetrachloroethane is used as the brominating agent for these reactions. The results are discussed in comparison with alternative methods in the literature.

Palladium-catalyzed hydrophenylation of bicyclic alkenes

Palladium-catalyzed hydrophenylation reactions of bicyclic alkenes were investigated. These reactions were found to be completely chemo- and stereoselective, giving only exo products on the less substituted double bonds of bicyclic alkenes in moderate to good yields. For unsymmetrical bicyclic alkenes, regioselectivities of 52:48 to 100:0 were observed with various substituents on the bicyclic alkenes.

Dibromocarbonyl Ylides. Deoxygenation of Aldehydes and Ketones by Dibromocarbene

The reaction of phenyl(tribromomethyl)mercury (4) with benzaldehyde-α-13C results in benzal-α-13C bromide and CO.The generality of this deoxygenation was shown by treatment of other aldehydes and ketones with mercurial 4 (1.8:1, benzene, 80 deg C, 4 h): , Ph (46), Et (35), i-Pr (39), t-Bu (19); Ph, Ph (6), Ph, Me (15), Me, Me (16), Et, n-Bu (19), Me, c-C3H5 (20), c-C3H5, c-C3H5 (20), cyclohexanone (38), cyclopentanone (19), norcamphor (46).Additional products in selected cases include (for acetophenone) α-bromostyrene, (for cyclohexanone) 1-bromocyclohexene and 1,1-dibromocyclohexane, (for norcamphor) 2,2-dibromonorbornane, 1,2-dibromonorbornane, 2-bromo-2-norbornene and 1-bromonorbornene, and (for pivaldehyde) 1,1-dibromo-2,2-dimethylpropane.The yields of CO from the treatment of a series of benzaldehydes with mercurial 4 (1.8:1 benzene, 80 deg C, 20 h) are given in parentheses: ArCHO (percent CO), 4-MeO (81), 4-Me (61), 3-Me (55), H (50), 4-F (46), 3-MeO (58), 4-Cl (46), 4-Br (47), 3-Cl (34), 3,4-Cl2 (27).A Hammett-type correlation of log (yield)/(yield)0 vs. ? gave ρ = -0.50 (r = 0.94).

DEOXYGENATION OF ALDEHYDES AND KETONES; A NEW GENERAL REACTION OF DIBROMOCARBENE AND DIBROMOCARBONYL YLIDES

The treatment of a variety of aldehydes and ketones with phenyl(tribromomethyl)mercury results in the production of carbon monoxide from the deoxygenation of the carbonyl group by dibromocarbene.
