nickel 0 Triethyl Phosphite complex catalyzed allylic substitution with retention of regio and stereochemistry
Organic Letters, 2007Co-Authors: Yasutaka Yatsumonji, Yusuke Ishida, Akira Tsubouchi, Takeshi TakedaAbstract:Nickel(0) Triethyl Phosphite complex-promoted reaction of allylic acetates with thiols produced allylic sulfides with retention of configuration without allylic rearrangement. A similar reaction of allylic acetates with alcohols and phenols also proceeded with retention of regio- and stereochemistry.

stereo recognizing transformation of e alkenyl halides into sulfides catalyzed by nickel 0 Triethyl Phosphite complex
Tetrahedron, 2006Co-Authors: Yasutaka Yatsumonji, Akira Tsubouchi, Orie Okada, Takeshi TakedaAbstract:Abstract (E)-Alkenyl halides were transformed into (E)-alkenyl sulfides by the nickel(0) Triethyl Phosphite complex-catalyzed reaction with thiols, whereas (Z)-alkenyl halides gave alkynes under the same reaction conditions. Aryl halides were also transformed into aryl sulfides using the same reagent system.

a critical overview of the kabachnik fields reactions utilizing trialkyl Phosphites in water as the reaction medium a study of the benzaldehyde benzylamine Triethyl Phosphite diethyl Phosphite models
Heteroatom Chemistry, 2014Co-Authors: Gyorgy Keglevich, Erika Balint, Reka Kangyal, Maria Balint, Matyas MilenAbstract:alpha-Aminophosphonates may be synthesized by the three-component condensation of oxocompounds, amines, and dialkyl Phosphites or trialkyl Phosphites. In the latter case, mostly water is the reaction medium and a catalyst is also needed. This approach has been studied critically by us, exploring the background of this version of the Kabachnik-Fields condensation. The possibilities for the Kabachnik-Fields condensation of benzaldehyde, benzylamine, and Triethyl Phosphite or diethyl Phosphite including the accomplishment in water were studied in detail.
