Abstract

By the reactions of a $C_{2}$-chiral ligand, (+)-11S,12S-bis[2,2'-(diphenylphosphino)benzanilido]-9,10-dihydro-9,10-ethanoanthracene(6) with $[\pi-allyl chloroplatinum(II)]_4$, and $CpCo(CO)_2$ respectively, three new complexes, ($\pi$-allyl)platinum(II)(+)-11S,12S-bis[2,2'-(diphenylphosphino)benzanilido]-9,10-dihydro-9,10-ethanoanthracene perchlorate(1), ($\pi$-allyl)platinum(II)(+)-11S,12S-bis[2,2'-(diphenylphosphino)benzanilido]-9,10-dihydro-9,10-ethanoanthracene chloride(2), ($\eta^5$-cyclopentadienyl)cobalt(I)-(+)-11S,12S-bis[2,2'-(diphenylphosphino)benzanilido]-9,10-dihydro-9,10-ethanoanthracene(3) were prepared. $\eta^3$-Cyclohexenyl)palladium(II)1,2-bis(diphenylphosphino)ethane perchlorate(4) was obtained by the reaction of ($\eta^3$-cyclohexenyl)palladium(II) chloride dimer with a symmetric ligand, 1,2-bis(diphenylphosphino)ethane and lithium perchlorate. These complexes were identified by NMR-, IR-, and Mass-Spectrophotometers and elemental analyzer.

C2-손대칭 리간드(chiral ligand)의 한 종류인 (+)-11S,12S-bis [2,2'-(diphenylphosphino)benzanilido]-9,10-dihydro-9,10-ethanoanthracene과 백금과 코발트를 포함하는 착물과 각각 반응시켜, 세 종류의 새로운 착물인 $\pi$-allyl Pt(+)-11S,12S-bis[2'-(diphenylphosphino)benzanilido]-9,10-dihydro-9,10-ethanoanthracene perchlorate, $\pi$-allyl Pt(+)-11S,12S-bis[2,2'-(diphenylphosphino)benzanilido]-9,10-dihydro-9,10-ethanoanthracene chloride, (${\eta}$5-cyclopentadienyl) Co -(+)-11S,12S-bis[2,2'-(diphenylphosphino)benzanilido]-9,10-dihydro-9,10-ethanoanthracene를 얻었다. 그리고 (${\eta}$3-cyclohexenyl) Pd 착물과 대칭리간드인 1,2-bis(diphenylphosphino)ethane 과 반응시켜 새로운 착물, (${\eta}$3-cyclohexenyl) Pd1,2-bis(diphenylphosphino)ethane perchlorate를 생성하였다. 이들 착물은 NMR-, IR-, Mass-spectrometer, 원소분석등의 각종 화학분석기기에 의해 각각 확인되었다.
