Information about reproducing material from RSC articles with different licences NMR spectra of compounds 7 and 8. Acceptorless dehydrogenation of alcohol is a green and atom-economic alternative, which provides aldehyde (or ketone) without the use of sacrificial acceptor molecules and the side product is molecular hydrogen. Dehydrogenation of alcohols by three iridium pincer complexes, IrH(Cl)[2,6-(tBu2PO)2C6H3] (1), {IrH(acetone)[2,6-(tBu2PO)2C6H3]}{BF4} (2), and IrH(Cl)[{2,5-(tBu2PCH2)2C5H2}Ru(C5H5)] (3), is reported, in both the presence and the absence of a sacrificial hydrogen acceptor.

Dehydrogenation of secondary alcohols proceeds in a catalytic mode with turnover numbers up to 3420 (85% conversion) for acceptorless dehydrogenation of 1-phenylethanol. 4 Questions . DFT computations indicate an outer‐sphere mechanism and support the importance of an acceptor to achieve this transformation under milder conditions.
