A series of MClx/CMS catalysts were prepared by wet impregnation with various types of metal chlorides (NiCl2, CuCl2, AlCl3, CoCl2, FeCl3, ZnCl2) on CMS support and further heat treated at mild temperature. The supported catalysts showed catalytic synergistic effect (~60% of conversion) and 100% selectivity in hydroamination of cyclohexene under mild reaction condition (60°C). Furthermore, the influence of reaction parameters and supports on activity of the catalyst was also investigated. The MClx/CMS catalysts can be recovered for reuse for several runs with little reactivity loss (~5%) and easily handled under the described reaction conditions. © 2013 Taiwan Institute of Chemical Engineers.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Cyclohexenes,Hydroaminations,Lewis Acid,Mesoporous Silica,Metal chlorides[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Chiral mesoporous silica,Cyclohexene,Hydroamination,Lewis acid,Metal chlorides[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]The authors would like to acknowledge USM RU (1001/PKIMIA/814127 and 1001/PKIMIA/811264) research grants for financial support.
