High Trans-1,4（Co）Polymerization of β-Myrcene and Isoprene with an Iminophosphonamide Lanthanum Catalyst

β-Iminophosphonamide ligated lanthanum bis（benzyl） complex（NPNDipp）La（CH2Ph-4-Me）2（THF）（NPNDipp = Ph2P（NC6H3iPr2-2,6）2）, upon activation of Al Et3 and [Ph3C][B（C6F5）4], exhibited high catalytic activity and high trans-1,4 stereoselectivity for the polymerization of bio-sourced b-myrcene（MY）. Based o...

Summary:β-Iminophosphonamide ligated lanthanum bis（benzyl） complex（NPNDipp）La（CH2Ph-4-Me）2（THF）（NPNDipp = Ph2P（NC6H3iPr2-2,6）2）, upon activation of Al Et3 and [Ph3C][B（C6F5）4], exhibited high catalytic activity and high trans-1,4 stereoselectivity for the polymerization of bio-sourced b-myrcene（MY）. Based on which, a series of novel trans-1,4 regulated elastomers could be generated by random/block copolymerization of MY and isoprene（IP）.
