The P=icr;S functional group in (η2-PCy2S)Mn(CO)4 (1) undergoes cyclocotrimerization with t-butyl propynoate to give the isomeric compounds 3a und 3b in a 1 : 1 ratio. Oxidation of 3a and 3b with (NH4)2[Ce(NO3)6] gives thiophene 4. Compounds 3a and 3b were characterized by use of MS spectrometry and IR, 31P1H}, 1H, and 13C1H} NMR spectroscopy.
在P = ICR; S于(η官能团2 -PCy 2 S)的Mn(CO)4(1)经历cyclocotrimerization用叔丁基
丙炔,得到异构体化合物3A UND 3b中以1:1的比例。用(NH 4)2 [Ce(NO 3)6 ]氧化3a和3b得到
噻吩4。化合物3a和3b通过MS光谱和IR,31 P 1 H},1 H和13 C 1来表征1 H NMR光谱。
