When the carbocation is the very reactive tertiary adamantane carbocation ( as judged from diminished rate of solvolysis ) this difference is only a factor of 10.
12.
Where the and are the solvolysis rate constants for a certain compound in different solvent systems and in the reference solvent, 80 % aqueous ethanol, respectively.
13.
The parameter " m " is a parameter measuring the sensitivity of the solvolysis rate with respect to Y, the measure of ionizing power of the solvent.
14.
Because the initial solvolysis step in this reaction involves a single molecule dissociating from its leaving group, the initial stage of this process is considered a uni-molecular reaction.
15.
In a series of acetolysis experiments, Winstein et al . observed that the solvolysis reaction occurred empirically faster when the tosyl leaving group was in the anchimeric assistance invoked by the " cis " isomer.
16.
In the first stage of this reaction ( solvolysis ), the C-L bond breaks and both electrons from that bond join L ( the leaving group ) to form L " and R 3 C + ions.
17.
The reason behind the success of this catalyst is the fact that the ene-adduct-Me 2 AlCl complex can further react to afford methane and aluminum alkoxide, which can prevent proton-catalyzed rearrangements and solvolysis ( Figure 9 ).
18.
An example of this formation route is the reaction that led Winstein and Trifan to propose the delocalized structure of the 2-norbornyl cation . 2-norbornyl tosylates and brosylates form the 2-norbornyl cation through this route as an intermediate towards solvolysis.
19.
For example, the tris ( solvent ) Me 5 ) Rh ( Me 2 CO ) 3 ] ( PF 6 ) 2 undergoes solvolysis when heated in acetone, forming a difluorophosphate-bridged complex [ ( ? 5-C 5 Me 5 ) Rh ( ?-OPF 2 O ) 3 Rh ( ? 5-C 5 Me 5 ) ] PF 6.
