Professor Kampmeier s research interests focus on the mechanisms of organic and organometallic reactions. Much of his past effort has been directed to the study of free radical additions, eliminations and displacements, and to questions concerning the stereochemical requirements of free radical displacement reactions. Studies of free radical displacements at sulfur led into the chemistry of hypervalent radicals, R 4 P . , R 3 S . , and R 2 I . , and the associated electron transfer chemistry. Recent work has focused on the reductive cleavage of sulfonium salts.
Photochemical reductants are especially useful for mechanistic studies.
Their conversion to s -radicals and subsequent cleavages are stereoelectronically constrained.
