Abstract

Abstract Substituted η 4-[3(E),5(E)-heptadien-2-ol)Fe(CO) 3 complexes 10a,b, 11a,b or the corresponding acetate derivatives 14, 20, 23, 25 and 28 undergo highly stereoselective Lewis acid mediated substitution reactions with various nucleophiles, including R 3Al reagents, ketene silyl acetals, allyltributylstannane, allyltrimethylsilane, and trimethylsilylazide. Evidence is presented that these reactions proceed with retention of configuration.
