A series of new PC(sp3)P pincer ligands possessing hemilabile
alkoxyl side arms as well as their iridium complexes are reported.
All new organometallic compounds were structurally characterized including
X-ray analysis. The hemilability of the side arms was probed by reactions
with CO, revealing the reversible coordination. The catalytic activity
of the new complexes was tested by iridium-catalyzed transfer dehydrogenation
of alkanes under mild conditions.
