中文摘要 | 茂雙羰亞硝基鉻基,弗洛笙基酮7 經氯化氫氣體與isoamyl nitrite 作氯化/ 亞硝基化可得氯茂雙羰亞硝基鉻基、弗洛笙基酮8,產率為68%與碘化鉀作用 ,可生成茂碘雙羰亞硝基鉻基。弗洛笙基、酮9,產率為58%。利用2D- HetCOR核磁共振光譜儀技術可確定8及9的Cp(Cr)及Cp��(Fe)環上C(2,5) 及C(3,4)之化學位移。 |
英文摘要 | Chlorination/nitrosylation of[η��-(ferrocenoyl) cyclopentadienyl] dicarbonylnitro- sylchromium (hereafter called cynichrodenylferrocenylketone)7 with hydrogen chloride/ isoamyl nitrite gives chloro[ η�� -(ferrocenoyl) cyclopentadienyl]dinitrosylchromium 8 in 68% yield. 8 was converted to [ η�� -(errocenoyl) cyclopentadienyl] iododinitro- sylchromium 9 with potassium iodide in 58% yield.The chemical shifts of H(2,5) protons and C(2-5) carbons of Cp ring in �� H and �C CNMR spectra, respectively has been assigned unequivocally using 2D-HetCOR NMR spectroscopy for compounds 8 and 9. |
