Exploring (Ph2PCH2CH2)2E ligand space (E = O, S, PPh) in RhI alkene complexes as potential hydroacylation catalysts

The ligands (Ph2PCH2CH2)2E (E = O, S, PPh) have been used to form a variety of RhI cations [Rh{(Ph2PCH2CH2)2E}(alkene)] + (alkene = methyl acrylate, trimethylvinylsilane). Variable-temperature NMR spectroscopy shows that the methyl acrylate ligands undergo a fluxional process on the metal, via a 1-carbonyl intermediate, while the trimethylvinylsilane complexes cannot access this intermediate and do not undergo the same process. Their reactivity in hydroacylation reactions with 1-pentanal have been investigated, and these studies further suggest the important role that a chelating substituent next to the aldehyde might play in productive hydroacylation. A variety of Rh I cations [Rh{(Ph2PCH2CH2) 2E}(alkene)]+ (E = PPh, S, O; alkene = methyl acrylate and trimethylvinylsilane) have been prepared and their fluxional behaviour investigated by variable-temperature NMR spectroscopy.
