Abstract
Palladium(II)-promoted vicinal diamination of N-alkenylbenzimidazoles has b een investigated. Dichlorobis(1(alkenyl)benzimidazole)palladium(II) complex es were identified as initial reaction products which proved to be rather i nert to the subsequent oxidative diamination required in the process. Inste ad, they were readily reduced by KBH4 to give the corresponding 1-alkylbenz azoles as the main reaction products. The crystal structure of the isolated complex trans-dichlorobis(1 -(3-butenyl)benzimidazole)palladium(II) was de termined by X-ray diffraction analysis. (C) 1999 Elsevier Science Ltd.
