Popis:	A series of cationic and dicationic Ru-arene complexes with Binap (1a) and MeO-Biphep (1b) have been prepared. 13C NMR studies are shown to be useful in connection with recognising the 6e-bonding mode of 1a and 1b in the dications [Ru(1a or 1b)(η6-arene)](SbF6)2 (8,9). Reaction of 8,9 with: (a) (Bu4N)(Ph3SiF2) leads to a cyclometallated product which arises via P—C bond breaking and P—F bond making; (b) methanol provides a straightforward synthesis of the corresponding hydrides. 13C NMR p-cymene chemical shifts are reported.Key words: P—C bond cleavage, 6e donors, cyclometallation, hydrides, 13C NMR.
