abstract

  • The reaction of cis-(CO) 4 Fe[Si(CH 3 ) 3 ] 2 (I) with CH 3 OSi(CH 3 ) 3 and C 6 H 5 CH 2 -OSi(CH 3 ) 3 at 80°C affords good yields of [(CH 3 ) 3 Si] 2 O and the deoxygenation products RSi(CH 3 ) 3 (R CH 3 , C 6 H 5 CH 2 ). These reactions are proposed to occur via (CO) 4 Fe(R)Si(CH 3 ) 3 intermediates. This is supported by the observed formation of cis-(CO) 4 Fe(CH 3 )Si(CH 3 ) 3 (II) during the more rapid reaction of I with (CH 3 ) 2 O; subsequent (CH 3 ) 4 Si elimination occurs. With (C 6 H 5 CH 2 ) 2 O, I reacts at 80°C to yield C 6 H 5 CH 2 Si(CH 3 ) 3 and C 6 H 5 CH 2 OSi(CH 3 ) 3 as primary products. With C 6 H 5 CH 2 OCH 3 , I effects regioselective benzyloxygen bond cleavage. © 1981.
