, (2008/06/13)
Chips mounted into substrates are often encapsulated with a cured epoxy which is insoluble. The invention herein is the discovery that diepoxides with ketal linkages are soluble. This permits encapsulating chips, testing them for goodness and removing the

Initial formation of a vinyl ether 2 by treatment of a primary alcohol 1 with ethyl vinyl ether in the presence of mercury (II) acetate followed by treatment with the same or a different alcohol in the presence of p-toluenesulfonic acid affords the symmetrical and unsymmetrical acetaldehyde acetals 3 in good overall yield. The method is easily scaled up and represents a significant improvement over currently available procedures.
