Eu(III) AND Tb(III) COMPLEXES BASED ON DIPHENYL(PYRIMIDIN-2-YL)PHOSPHINE OXIDE: SYNTHESIS, STRUCTURE, AND PHOTOLUMINESCENT PROPERTIES
Abstract: Coordination compounds [Eu{Ph2P(O)Pym}2(NO3)3] (1) and [Tb{Ph2P(O)Pym}2(MeOH)(NO3)3] (2) are synthesized by the interaction of Eu(III) and Tb(III) nitrates w
Visible-Light-Promoted Transition-Metal-Free Phosphinylation of Heteroaryl Halides in the Presence of Potassium tert-Butoxide
A novel visible-light-promoted C-P bond formation reaction in the absence of both transition metal and photoredox catalysts is disclosed. By employing easily available and inexpensive heteroaryl chlorides/bromides as substrates, a variety of heteroaryl phosphine oxides were obtained in moderate to good yields. This strategy provides a simple and efficient route to heteroaryl phosphine oxides.
Nickel-catalyzed C-P cross-coupling of diphenylphosphine oxide with aryl chlorides
A novel protocol for the preparation of various diarylphosphine oxide compounds via a Ni-catalyzed cross-coupling of aryl chlorides with R 2P(O)H has been developed. Notably, this process exhibits the following very attractive features: (i) the process is simpler and operates under mild reaction conditions; (ii) the process is generally cheaper in part because the more accessible aryl chloride is used to form the C-P bond; (iii) the process avoids the need for simultaneous preparation and use of Ar 2P(O)M.
