Anilin temelli aminofosfinler ve katyonik bis fosfino amin Ru II kompleksleri: Ketonların transfer hidrojenasyonundaki katalitik aktiviteleri

Hidrojen transfer indirgenme reaksiyonu, ifllem kolaylığı avantajından dolayı sentez alanında çalıflankimyacıların ilgisini çekmektedir. Bu bağlamda, [Ru η-p-simen µ-Cl Cl]2 kompleksinden yola çıkarakNPP ve NHP ligandlarının bir dizi Ru II kompleksi sentezlendi ve bu kompleksler analitik ve spektroskopikmetotlarla tam olarak karakterize edildi. 1 - 4 kompleksleri hidrojen kaynağı olarak izopropil alkol varlığındabirçok alkil ve aril alkil ketonların sekonder alkollere transfer hidrojenasyonunu katalizlemektedir.

Aniline based aminophosphine and cationic bis phosphino amine Ru II complexes: Investigation of catalytic activity in transfer hydrogenation of ketones

Hydrogen transfer reduction processes are attracting increasing interest from synthetic chemists in viewof their operational simplicity. For this aim, a series of Ru II complexes with the NPP and NHP ligandswere synthesized starting from the complex [Ru η6-p-simen µ-Cl Cl]2. The complexes were fullycharacterized by analytical and spectroscopic methods. Complexes 1-4 catalyze the transfer hydrogenationof a variety of simple alkyl and aryl alkyl ketones to secondary alcohols in the presence of iso-PrOH as thehydrogen source. Notably 3 acts as an excellent catalyst giving the corresponding alcohols in excellentconversions up to 99% TOF:198 h-1
