Table 1. Catalytic dehydrogenation of cyclooctane (COA) to cyclooctene (COE) with tert-butylethylene (TBE) as a hydrogen acceptor promoted by (POBOP)Ru(H)(PPh₃) (3).


COA, equiv.	TBE, equiv.	3, equiv.	Atmosphere	TON ^a
3000	3000	1	N₂	77 ± 5
5700	1000	1	N₂	400 ± 8
5700	1000	1	Air	288 ± 8

^aExperiments were carried out at 170 °C for 2 h in sealed tubes. TONs were determined from ¹H NMR spectra of reaction mixtures with the use of naphthalene as an internal standard. Each entry corresponds to three independent experiments.
