Regio‐ and Stereocontrolled Nucleophilic Addition Reactions of An Unsymmetrically Disbustituted Butadiene η⁴‐Molybdenum Cationic Complex

Abstract

The reactions of a new cationic complex, [Cp(CO)2Mo(η4‐2‐methyl‐3‐SPh‐C4H4)]+ PF−6 (3), with carbon, hydride, and nitrogen nucleophiles were found to give only the C‐1 addition products in good yield. The X‐ray crystal structures of two of the addition products 4a and 4e confirm the regio‐ and stereochemistry of the nucleophilic additions.
