“…We have previously studied the CPL properties of pinene-containing cyclometalated Pt(II) complexes with chiral-at-metal and helical chirality [ 50 , 51 , 52 , 53 ]. Pinenes with defined carbon stereocenters would control the specific configuration and stacking of Pt(II) complexes [ 50 , 51 , 52 , 53 , 54 , 55 ]. In this work, a couple of pinene-functionalized phosphorescent tetradentate Pt(II) complexes ((−)- 1 and (+)- 1 ) with fused 5/6/6 metallocycles have been prepared under the protection of argon ( Scheme 1 ).…”

The first example of the palladium‐catalyzed sp3 C‐H bond activation in a monoterpene‐based compound has been observed in the reaction of PdCl2 with a (+)‐3‐carene‐based ligand HL (HL = N‐((1aS,3S,7bR)‐1,1,3‐trimethyl‐7‐phenyl‐5‐(pyridin‐2‐yl)‐1a,2,3,7b‐tetrahydro‐1H‐cyclopropa[f]quinolin‐3‐yl)acetamide), which yielded the [PdLCl] complex. In contrast to the vast majority of C(sp3)‐H activation reactions which require prolonged heating and mixing due to the inert character of the corresponding bond, the reaction reported herein proceeds rapidly under mild conditions. A theoretical insight into the ligand deprotonation has been performed by DFT calculations. The mechanism of the C‐H activation involves (i) simultaneous coordination of the CH3 group of HL to the Pd2+ ion and decoordination of the Cl‐ anion with consequent formation of a Cl⋅⋅⋅H‐N hydrogen bond with the amide group, (ii) approximation of the out‐of‐sphere Cl‐ anion to one of the hydrogen atoms of the CH3 group mediated by the crane motion of the amide group and (iii) the ejection of the HCl molecule, which increases the entropy of the system and serves as a driving force for the reaction.
