1H NMR測定の結果、-5~150ppmという幅広い範囲に亘ってブロードなピークが観測されたことから、表題化合物は常磁性であると判明した。また、-150~250ppmの範囲においては、31P NMRではピークが観測されなかった。
ジクロロ{(1S,1’S)-N,N’-[1,2-フェニレンビス(メチレン)]ビス[2-(ジフェニルホスフィノ)-1-フェニル-エチルアミン]}鉄(II)(構造式(FeCl2[(S,S)-1B-3]))の合成(Eq.27)
1H NMR測定の結果、-10~140ppmという幅広い範囲に亘ってブロードなピークが観測されたことから、表題化合物は常磁性であると判明した。また、-150~250ppmの範囲においては、31P NMRではピークが観測されなかった。

更に、配位形式の異なるcis-β-RuCl2(1B-1)もまた、cis-α体同様の優れた触媒活性を有していた(実施例27)。
従ってこれらの錯体は、従来のPNNP四座配位子を有するルテニウム錯体(前記の特許文献1及び非特許文献1)と比較して、大幅に触媒活性が向上していることがわかる。
また、本発明の遷移金属錯体の中でも、SNNS四座配位子を有するルテニウム錯体であるRuCl2(1B-6)は、5MPaという高圧の水素ガスを必要とするものの、従来のSNNS四座配位子を有する従来のルテニウム錯体(前記の非特許文献2)ではそもそも困難だった、ケトン類よりも反応性に乏しいエステル類の水素添加反応を効率よく進行させることが明らかとなった(実施例29)。
