• β-Imidophosphonamido ligated lutetium alkyl complex（NPNDipp）Lu（CH2Si Me3）2（THF）（NPNDipp = Ph2P（NC6H3iPr2-2,6）2） with the activation of AliBu3 and [Ph3C][B（C6F5）4] exhibited high catalytic activity, medium syndio-（rr = 66%） but remarkably high 3,4-regioselectivity for the polymerization of β-myrcene（MY）. In sharp contrast, high isotactic 3,4-polymyrcene（PMY）（mm = 95%） was obtained by the precursor（NPN^Et）Lu（CH2Si Me3）2（THF）（NPN^Et = PPh2（NC6H3^iPr2-2,6）（NC6H4-Et-2）） with less bulky substituents on the N-aryl ring.
