Research Abstract	我々はこれまでの研究で、有機ホスフィンを補助配位子とするモリブデンおよびタングステンの窒素錯体について、その配位窒素分子をピロールおよびアミノピロールへと変換するとともに原料である窒素錯体を再生するサイクルを完成させている。今年度はこの反応を触媒的に進行させるための手段として、ヒドラジド錯体の生成やN-N,N-W(Mo)結合の開裂の際に必要な水素を、近傍の他の金属サイトで活性化された水素分子から供給できるような多核金属反応場を設計を行ってきた。実際、本研究においてカチオン性ルテニウム錯体[RuCl(dppp)_<>]^+を水素の活性化サイトとして用いることで、常圧水素下55℃という穏和な条件のもとでタングステン窒素錯体[W(N_2)_2(PMe_2Ph)_4]からアンモニア、アジンを合成できることが判明し、触媒的な窒素固定反応への展開の可能性を示すことができた。カルコゲニドクラスターの合成と反応性についても、[Cp^IrCl(μ-SH)_2IrCp^Cl]、[(Et_2NCS_2)Mo-S(μ-S)_2MoS(S_2CNEt_2)]のようなメタロリガンドをクラスター合成ユニットとして利用する合成法の開発により、各種の貴金属カルコゲニドクラスターの合理的合成を行うことができた。今後は貴金属の種類やクラスター構造を自在に制御しつつ、さらに多核の構造を有するクラスター合成まで展開するとともに、本研究で見出された新規クラスターの小分子に対する反応性、触媒活性の開拓を行っていく。
