The change of the anionic charge is clearly evidenced by the shift of the νCO bands of the cluster in the IR spectrum. 2) The fact that a MCC retain the same structure upon protonation/deprotonation, but its charge changes, can be further assessed by SC-XRD, if single crystals are ...

The high regio‐ and stereoselectivity of the reaction 1 → 2 points to a mechanism involving a transannular 1,5 hydrogen migration; the CH activation probably takes place via a cyclic, seven‐membered transition state. This was the result of a detailed mechanistic study of the PdCu catalyzed ...
The reaction of propyne with the cis and trans isomers of 2-methylcyclohexanoyl tetrafluoroborate proceeds with the formation of the products of 1,5-hydride shift, in which connection its direction depends on the configuration of the reagent....

Novel access to methyl substituted polyketide structural units through 1,5-hydride shift and ether transfer: application to the syntheses of diospongins A and B and towards lyngbyaloside c.This dissertation comprises three major components that sequentially describe the development of three ...
In products of Stevens 3,2-rearrangement of ammonium salts containing alongside alkoxycarbon- ylmethyl also 3-phenyl-2-propynyl group an intramolecular 1,5-hydride shift is observed resulting in immonium salts which transform into aminoesters of enamine structure. The hydrolysis of the latter ...
