Abstract

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.

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.
