Lanthanoid induced C-F activation of all fluorine atoms of one CF₃ group

The lanthanum formamidinate complex [La(CF3Form)3] CF3FormH = N,N-bis(2-trifluoromethylphenyl)formamidine , which has six La-F interactions in the solid-state structure, readily undergoes C-F activation of all fluorine atoms of one CF3 group to give LaF3, and two isomeric polytrifluoromethylphenyl-substituted polyamidines, one containing a 1,2,3,4-tetrahydroquinazoline heterocyclic core.
