there are some unusual examples of very stable carbocations that take the form of organic salts. Crystal violet is the common name for the chloride salt of the carbocation whose structure is shown below. Notice the structural possibilities for extensive resonance delocalization...
structure of C1-C7 group which may be saturated or unsaturated and cyclic or non-cyclic, and which optionally may be substituted with any of the above preceding groups, including hydrocarbon compounds acetaldehyde, butyraldehydej glutaric dialdehyde, crotonaldehyde, benzaldehyde, acetone, methyl vinyl ...
Alternatively, functional groups may allow for crosslinking of the polymer following exposure to a stimulus to confer increased stability on the resultant structure. Comonomers may be selected from compounds of the general formula VII in which R23 is selected from the group consisting of hydrogen,...
The (001) surface of crystalline AlCl3 is the natural cleavage plane and its structure is predicted via first principles calculations. The chlorine ions in the outermost layer of the material mask the Al3+ ions from the external gas phase. Hence, the experimentally found catalytic properties of ...

The structure of sialyl Lewis X is shown below as Formula A. The present invention provides a class of linkable sialyl Lewis X analogs of structural Formula 1. These analogs have a conjugatable nucleophilic amino group, which facilitates preparation of multimeric SLeX compositions with enhanced bindi...
