Let s compare the carbocation intermediates for addition of a hydrogen halide (HX) to an unsymmetrical alkene of the type RCH=CH2 (a) according to Markovnikov s rule and (b) opposite to Markovnikov s rule (a) Addition according to Markovnikov s rule... 

We recall some definitions which are useful in the work to follow. The smallest a-algebra containing all compact sets in r 9r is called the Borel a-algebra (Landkof, 1966). Any a-additive real-valued function defined on the Borel a-algebra which is finite for all compact sets B c r 9r is called a measure on 9r. Thus, for a measure p and a set A, the a-additivity means...

In the presence of aqueous acetic acid the 4//-azepi ne 9 yields the hydroxy derivative 10 a. Addition of methanol, in the presence of Sephadex LH20, and cyanide ion in the presence of palladium(II) acetate, are also successful and yield 4,5-dihydro-l //-azepines 10b and 10c, respectively.113... 

Consider the possibility that the reaction proceeds in stages (a) addition of C1 to a vacant axial position, (b) loss of any equatorial Cl", (c) collapse of this structure to the stable square-planar geometry. This sequence is shown ...
