electron-deficient arenes, including Lewis basic heterocycles. Here we report a highly Markovnikov-selective, dual-catalytic olefin hydroarylation that tolerates arenes and heteroarenes of any electronic character. Hydrogen atom transfer controls the formation of branched products and arene halogenation specifies attachment points on the aromatic ring. Mono-, di-, tri-, and tetra-substituted alkenes yield Markovnikov
The present invention provides a polyvinyl ether compound containing an alkylene glycol or polyoxyalkylene glycol unit and a vinyl ether unit in a molecule and having a molecular weight in the range of 300 to 3,000. It shows high volume resistivity and a high viscosity index, so it can be favorably used as lubricating oil for a compression refrigerator.
The invention relates to novel compounds of the formula (I)
in which X, Y, Z, A, B and G have the meanings given above,
to a plurality of processes and intermediates for their preparation and to their use as pesticides and/or herbicides.
Moreover, the invention relates to selective herbicidal compositions comprising, firstly, the phenyl-substituted bicyclooctane-1,3-dione derivates 33 and, secondly, a crop plant compatibility-improving compound.
The present invention furthermore relates to increasing the activity of crop protection compositions comprising in particular phenyl-substituted bicyclooctane-1,3-dione derivates by adding ammonium salts or phosphonium salts and, if appropriate, penetrants, to the corresponding compositions, to processes for their preparation and to their use in crop protection as insecticides and/or acaricides and/or for preventing unwanted plant growth.

The stereo- and regio-chemistry of two step additions of positivehalogenelectrophiles to 5-methylene-2-phenyl-1,3-dioxane, 1-tert-butyl-4-methylenecyclohexane and 3-methoxy-2-(methoxymethyl)prop-1-ene have been determined. The direction of initial electrophile attack is in line with the frontier orbital and electrostatic considerations described by us previously. The regiochemistry of addition is
