Treatments of (η4-cyclohexa-1, 3-diene) Fe (CO) 3 complex with 1.2 equivalents of PhMe2SiLi, followed by quenching the reactive intermediate with CF3COOH generated 1- dimethyl (phenyl) silylcyclohex-1-ene and with 2-(phenylsulfonyl)-3-phenyloxaziridine produced [η4-2-dimethyl (phenyl) silylcyclohexa-1, 3-diene] Fe (CO) 3 complex as the major product. Additions of the silyl anion to (η6-arene) Cr (CO) 3 and (η6-cyclohepta-1, 3, 5- ...
