摘要
The new pyrrolyl-linked pincer-type ligand, [C 4 H 2 NH(2-CH 2 NH t Bu)(5-CH 2 NMe 2 )] (1), that has been employed conveniently in high yield by treatment of (2-t-butylaminomethyl)pyrrole with 1 equiv of formaldehyde and dimethylamine hydrochloride each in diethylether and its corresponding aluminum derivative, [C 4 H 2 N(2-CH 2 NH t Bu)(5- CH 2 NMe 2 )]AlH 2 (2), that has been generated from Me 3 N.AlH 3 using diethylether as a solvent are described. Furthermore, reactions of 2 with 2 equiv of either 1,3-diphenylpropane-1,3-dione in diethylether or phenyl thioisocyanate in dichloromethane interestingly formed [C 4 H 2 N(2-CH 2 NH t Bu)(5-CH 2 NMe 2 )]Al(PhCOCHCOPh) 2 (3) and [C 4 H 2 N(2-CH 2 NH t Bu)(5-CH 2 NMe 2 )]Al(SCHNPh) 2 (4), respectively, following deprotonation or hydroalumination reaction kinetics under a dry nitrogen environment. All of the compounds have been subjected to the X-ray diffraction technique in the solid state as well as characterized by NMR spectra. © 2009 American Chemical Society.
