The arene complexes, (η6-C6H6)Cr(CO)2(CX) (X = S, Se), react with excess CO gas under pressure in tetrahydrofuran at about 60° C to produce the Cr(CO)5(CX) complexes in high yield. The IR and NMR (13C and 17O) spectra of these complexes are in complete accord with the expected C4v molecular symmetry. Like the analogous W(CO)5(CS) complex, both compounds react with cyclohexylamine to give Cr(CO)5(CNC6H11)
芳烃络合物,(η 6 -C 6 H ^ 6)的Cr(CO)2(CX)(X = S,Se)的,用过量的CO气体在压力下在四氢呋喃中反应,在约60℃下,以产生的Cr(CO)5(CX)络合物的高收率。这些配合物的IR和NMR(13 C和17 O)光谱与预期的C 4 v分子对称性完全一致。像类似的W(CO)5(CS)配合物一样,两种化合物都与环己胺反应生成Cr(CO)5(CNC 6 H 11)。但是,当W(CO)5时(CS)进行立体有择CO的取代与卤化物离子(Y -以形成反式- [W(CO)4(CS)Y] - ,两个铬chalcocarbonyl络合物显然经受CO和CX替代,得到的混合物[CR(CO )5 Y] -和反式-[Cr(CO)4(CX)Y] -。
