Scientific Career

Thesis Title	Rearrangements of Propargyl Selenoxides. Siloxyallyl- and Allenyllithium Reagents from Acyl Silanes.
Research Summary	Rick worked on several projects in the silyl ketone area, most notably the synthesis of allenyl silyl ethers by the addition of lithium acetylides to acyl silanes followed by alkylation of the allenyllithium reagent formed by Brook rearrangement.
