Shinohara, Koichi published the artcileN-Methylation of Aniline Derivatives with CO2 and Phenylsilane Catalyzed by Lanthanum Hydridotriarylborate Complexes bearing a Nitrogen Tridentate Ligand, Name: 4-Methoxy-N-methylaniline, the main research area is methyl aniline preparation; aniline methylation phenylsilane lanthanum hydridotriarylborate complex nitrogen tridentate ligand; lanthanum hydridotriarylborate complex nitrogen tridentate ligand preparation.
A lanthanum amide complex, La(L)[N(SiHMe2)2](thf) (L = N,N””-bis(pentafluorophenyl)diethylenetriamine dianion), upon activation with B(3,4,5-F2C6H2)3, showed excellent catalytic activity for N-methylation of N-alkylaniline derivatives with CO2 in the presence of PhSiH3. A catalytically active lanthanum hydridotriarylborate complex, [La(L)(thf)2][HB(3,4,5-F3C6H2)3], was generated via hydride abstraction from the Si-H moiety by moderate Lewis acid B(3,4,5-F2C6H2)3 in THF. DFT studies of the CO2 hydrosilylation step clarified the following multiple noncovalent interactions as key factors for locating the HB(3,4,5-F2C6H2)3 anion and B(3,4,5-F3C6H2)3 near the lanthanum center in the transition states of CO2 reduction and Si-O bond formation: (1) π-π interaction between the electron-deficient C6F5 ring on ligand L and the 3,4,5-F3C6H2 ring of the HB(3,4,5-F3C6H2)3 anion and (2) C-H···F hydrogen bonds between the ortho-C-H bond of B(3,4,5-F3C6H2)3 and the fluorine atoms of L.
