ZUNIGA, CÉSAR; SIERRA, DIEGO; OYARZO, JUAN  y  KLAHN, A. HUGO. METHOXYCARBONYLATION OF STYRENE BY PALLADIUM(II) COMPLEX CONTAINING THE DIPHENYLPHOSPHINOCYRHETRENE LIGAND. J. Chil. Chem. Soc. [online]. 2012, vol.57, n.2, pp. 1101-1103. ISSN 0717-9707.  doi: 10.4067/S0717-97072012000200009.

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%.
