입체선택적 유기합성반응을 위한 새로운 촉매 합성과 이의 응용 -Bisphosphonite-Rhodium 촉매합성-

Synthesis and Application of New Type Organometallic Catalyszt -Synthesis of Bisphosphonite-Rhodium Complexes-

새로운 형태의 촉매를 개발하기 위하여 bis(diethylamino)phosphine을 diol과 반응시켜 bisphosphonite를 합성하고, 이것을 bis(cycloocta-1,5-dienrhodium tetrarate)$[(COD)_2Rh^+BF_4\;^-]$와 반응시켜 rhodium(I)-bisphos-phonite complex를 처음으로 합성하였다. 이 유기금속화합물의 결정구조를 확인하였으며, 이들은 hydroformyl-ation반응에 효과적인 촉매로 이용될 수 있음이 밝혀졌다.

The new type ligand, bisphosphonites, were easily prepared through ligand exchange reaction of bis (diethylamino)phosphine with diols. These bisphosphonites reacted with $(COD)^2Rh^+BF_4\;^-$ to corresponding bisphosphonite-rhodium(I) comlexes, of which X-ray crystallography was for the first time investigated. This organometallic compound was applicated in hydroformylation reaction as catalyst, and proved to be very effective one.
