developed by copper‐catalyzed decarboxylative coupling of alkenyl, alkynyl carboxylic acids, and N‐benzylproline, respectively, with R2P(O)H (see scheme). All classes of products are important precursors for preparation of biologically active molecules and various phosphorus ligands. This finding represents the first example of copper‐catalyzed decarboxylative coupling to construct CP bonds.

The first nickel-catalyzed decarboxylative C–P coupling of a wide range of alkenyl acids with various P(O)Hcompounds, especially for H-phosphonates, has been developed, affording a versatile and efficient tool for the preparation of valuable (E)-1-alkenylphosphonates, (E)-1-alkenylphosphinate oxides, and (E)-1-alkenylphosphine oxides with high stereoselectivity and broad substrate applicability.

An efficient, mild, and generally applicable protocol for copper-mediated oxidativedecarboxylativecoupling of arylpropiolicacids with dialkyl H-phosphonates in water has been developed. Note that the reaction could proceed smoothly under air at relatively low temperature (60 °C), and the addition of isopropanol could successfully suppress the decomposition of dialkyl H-phosphonates in water.
synthesis of a vast variety of heteroatom‐containing cyclobutene‐triflones [bis(trifluoromethylsulfonyl)cyclobutenes] and cyclobutenones has been developed starting from heteroatom‐substituted alkynes and a pyridinium salt (a latent Tf2C=CH2 source). This powerful methodology, involving cyclization reactions, allows for the selective preparation of oxygen‐, nitrogen‐, bromine‐, chlorine‐, iodine‐, sulfur‐

and efficient route for the synthesis of alkynylphosphonates and ynamides by aerobic oxidative alkynylation of H-phosphonates and amides with both aliphatic and aromatic alkynes using our synthesized recyclable heterogeneous Cu–MnO catalyst has been developed. The phosphorylation was carried out under base- and ligand-free conditions, and in the presence of air as the sole oxidant. The reaction is compatible
