A consequence of the fact that shock-initiation occurs ahead of other reaction fronts (deflagration and low-order detonation) is that the precursor shock mechanism requires a backward-moving detonation front - a retonation to propagate from the point S. Such a front was observed photographically by Griffiths Groocock (Ref 10) (Ref 14, pp 51-2)...

Esters - vinyl ethers. The original publication (8, 83-84) mentioned that ethyl cetntc reacts with 1 to give ethyl isopropcnyl ether. More recent work1 has shown thul ihis conversion of esters to vinyl ethers is general and proceeds in high yields. The read ion rate is dramatically increased by the presence of donor ligands (THF, ( lhN). The solvent is benzene or toluene. Retone methylenation is possible, and Medially I lie rate is four limes Ihat of ester methylenation. Isolated yields are cited in Ihc examples.

From an analysis (an inaccurate one at that, but we cannot dwell on that here) of the conditions for appearance of the detonation wave, in particular based on the experimentally established fact of the appearance, at the point of detonation generation, of a reverse, so-called retonation, compression wave which propagates through the combustion products, Crussard [4] concludes... 

Transfer of the conditions (11) to a shock wave which is continuously igniting a gas in steadily propagating detonation is absolutely impermissible in this case there is no question of retonation waves. Any conditions more or less required for detonation to be generated have nothing at all to do with steady propagation. 

Retonation. A detonation which is delayed in developing, that is it does not start until the shock from a donor, thru a barrier, has proceeded for a distance known as induction distanoe , and then the detonation goes not only forward into fresh material, but also backward in the shocked material Ref Anon, Principles of Explosive Behavior , EngrgDesHndbk, AMCP 706-180 (1972), 12-15... 

Figure 20. Radial charge density plot for the retonant orbital in e-Ca scattering. The role of optimal theta (8opt = 0.3J radians) in the accumulation of electron density near the nucleus with the maximum at rmax = 9 a.u. is evident. The number of radial nodes identifies it as a 6p-type orbital.
