METHOXYCARBONYLATION OF STYRENE BY PALLADIUM(II) COMPLEX CONTAINING THE DIPHENYLPHOSPHINOCYRHETRENE LIGAND
The palladium-catalyzed methoxycarbonylation of vinylarenes has been investigated for the first time using phosphinocyrhetrene [(Ti5-C5H4PPh2)Re(CO)3] a non-metallocenic organometallic ligand. The catalytic system trans-[(T5-C5H4PPh2)Re(CO)3]PdCl2(NCMe)/PPh3 (1:2 ratio), carbon monoxide and methanol...

| Sumario: | The palladium-catalyzed methoxycarbonylation of vinylarenes has been investigated for the first time using phosphinocyrhetrene [(Ti5-C5H4PPh2)Re(CO)3] a non-metallocenic organometallic ligand. The catalytic system trans-[(T5-C5H4PPh2)Re(CO)3]PdCl2(NCMe)/PPh3 (1:2 ratio), carbon monoxide and methanol, in the presence of HCl as acidic promoter, showed good catalytic activity, excellent regioselectivity to the branched products and chemoselectivity up to 94%. |
