isothiocyanates (R3-C6H4-NCS; R3H (a), Me (b), OMe (c), NO2 (d)) with Fe(R2-NC)3(iPr-DAB) (7) (R2tBu or cHex) leads in a 1,3-dipolarcycloaddition reaction to novel [3.2.0] bicyclic compounds 10 into which two isothiocyanate molecules have been incorporated. A crystal structure determination revealed the unexpected insertion of an isothiocyanate via its CS moiety and the lack of coordination of the unreacted
对位取代的苯基异硫氰酸酯的反应(R 3 -C 6 H ^ 4 -NCS; R 3 H(一)中,Me(b),OME(Ç),NO 2(d))为Fe(R 2 -NC )3(我镨DAB)(7)(R 2 吨卜或ç十六进制)的引线在1,3-偶极环加成反应,以新颖〔3.2.0〕双环化合物10其中已掺入两个异硫氰酸酯分子。晶体结构测定表明,异硫氰酸酯通过其CS部分意外插入,并且未反应的亚胺氮原子缺乏配位。可变温度NMR实验显示动力学行为为10,其中涉及氨基和亚胺氮原子与铁原子的交换配位。
