Pt versus Au: Platinum-catalysed addition of nucleophiles to allenes follows a distinctly different pathway to the process catalysed by gold(I) complexes; the platinum catalyst leads to different products with indoles involving a bisindolylation reaction, whereas gold(I) gives allyl indoles from a single addition (see scheme).

A new platinum-catalysed dihydroalkoxylation of alienes is described to give aliphatic acetals by an unexpected attack of two molecules of methanol to the terminal carbon of the aliene moiety. Deuteration experiments suggest an unprecedented formal 1,3-dipolar addition of methanol to a zwitterionic platinum carbene as the key step. The first platinum-catalysed intermolecular carbonbased nucleophile addition to alienes is also reported.
