Abstract Chiral induction has been examined in the four diastereomeric products formed in a series of outer-sphere electron transfer reactions between the oxidants [Co(ox) 3 ] 3− , [Co(edta)] − , [Co(gly)(ox) 2 ] 2− , C 1 -cis ( N )-[Co(gly) 2 (ox)] − , [Co(en)(ox) 2 ] − , C 2 -cis ( N )-[Co(gly) 2 (ox)] − and trans ( N )-[Co(gly) 2 (ox)] − with [Co(( RR , SS )-chxn) 3 ] 2+ and [Co(( R , S )-pn) 3
摘要研究了在氧化剂[Co(ox)3] 3−,[Co(edta)]-,[Co(gly)(ox) )2] 2−,C 1-顺式(N)-[Co(gly)2(ox)]-,[Co(en)(ox)2]-,C 2-顺式(N)-[Co(gly) )2(ox)]-和反式(N)-[Co(gly)2(ox)]-与[Co((RR,SS)-chxn)3] 2+和[Co((R,S)- pn)3] 2+作为还原剂。产品; [Co((RR,SS)-chxn)3 -lel 3] 3+,[Co((RR,SS)-chxn)3 -lel 2 ob] 3+,[Co((RR,SS)-chxn)3 -lexn) 3 -lelob 2] 3+,[Co((RR,SS)-chxn)3 -ob 3] 3+和[Co((R,S)-pn)3] 3+的对应物种显示选择性的模式,其中根据反应物的大小和结构进行分析。氧化剂上伪C 3
