  Synthesis and Reactivity of Homoleptic α-Metalated N,N-Dimethylbenzylamine Rare-Earth-Metal Complexes

  摘要：

  A series of new homoleptic rare-earth-metal complexes as synthesized using salt metathesis reactions between LnCl(3) and alpha-K(DMBA) (Ln = La (1), Ce (2), Pr (3), Nd (4), Sm (5), Gd (6), Y (7); DMBA = N,N-dimethylbenzylamine). All seven complexes were found to be free of coordinating solvent, and no formation of any "-ate" species was observed. The ligands in complexes 1-7 displayed eta(4) coordination to the metal center. Subsequently, the reactivity of 1 and 7 was investigated via various protonolysis reactions using silylamines, anilines, and phenols to generate a diverse array of other homoleptic lanthanide complexes.

  The present invention relates to a novel catalytic system for polymerization, and more particularly for preparing conjugated diene polymers bearing a polar function at the chain end. This catalytic system is based on a metal salt of a rare-earth metal and, as alkylating agent, an organometallic compound based on a metal belonging to the 2 nd column or the 13 th column of the Periodic Table, capable of transferring a polar function to the diene elastomer during the conjugated diene polymerization step. The novel catalytic system makes it possible to reduce the steps for synthesizing a chain-end functionalized elastomer, while ensuring optimal functionalization, advantageously close or equal to 100%.

  PhCH(K)NMe2 and LiCH2NMe2 react with zirconocene or hafnocene chlorides in THF to give satisfactory yields of their (dimethylamino)alkyl derivatives. Cp2Zr(R)CH(Ph)NMe2 (R = Cl, 5; R = Me, 6) was prepared by treating Cp2Zr(R)Cl with PhCH(K)NMe2. Cp(eta-5-C5H4R)M(Cl)CH2N(CH3)2 (M = Zr, X = Cl, R = H, 7; M = Hf, X = Cl, R = H, 8; M = Zr, X = Cl, R = CPh(CH3)2, 11) was prepared by treating the appropriate metallocene dichloride with LiCH2N(CH3)2. Acidic reagents (CF3CO2H, CpMo(CO)3H, [n-Bu3NH][BPh4]) cleaved the methyl ligand from 6 and gave the -O2CCF3 complex (10), the -(mu-OC)Mo(CO)2Cp complex (12), or the solvated cation (13). Complex 7 did not react with excess LiCH2N(CH3)2, LiPh, MeI, CO(g) (1 atm), or Na(Hg), but a low yield of its methyl derivative was obtained by treating it with LiCH3. The inequivalence of the N-methyl groups in the H-1 NMR spectra of complexes 5, 6, and 10-13 at low temperatures showed that the CH(R)NMe2 ligands were bound in an eta-2 fashion. Simulation of the temperature-dependent H-1 NMR spectra of CDCl3 solutions of 11 gave DELTA-H double-ended-dagger and DELTA-S double-ended-dagger values of 17.1 +/- 0.8 kcal/mol and 2.3 +/- 2.7 eu, respectively, for N-methyl exchange. The Zr-N interaction energy in 11 can thus be estimated at 8 kcal/mol.
