The transition metal-free addition of phosphinoboronate ester Ph2PBpin (pin = 1,2-O2C2Me4) to heterocumulenes including carbodiimides, isocyanates, isothiocyanates and carbon dioxide has been investigated. The corresponding 1,2-addition products were readily prepared at room temperature without the need of a catalyst or added base. Addition of methanol to the compounds derived from addition of Ph2PBpin to carbodiimides, isocyanates, and isothiocyanates resulted in traditional hydrophosphination products. The methodology developed in this study provides a simple and elegant route for the generation of a wide range of functionalized phosphines. The phosphinoboronate ester Ph2PBpin also selectively and reversibly adds to CO2 at room temperature in a 1,2-manner.

The synthesis and characterization of benzimidazolin-2-iminato actinide(IV) complexes [(BimR1/R2N)An(N{SiMe3}2)3] (An = U, Th) (1-6) is reported. All complexes were obtained in high yields, and their solid state structures were established through single-crystal X-ray diffraction analysis. Using 1-6 as precatalysts, the addition of mono- and bifunctional E-H (E = N, P, C, O, S) substrates to various heterocumulenes, including carbodiimides, isocyanates, and isothiocyanates, was investigated, affording the respective addition products in high yields under very mild reaction conditions. Various amines were applicable to this reaction, indicating a large scope capability of amine nucleophiles for the insertion process.

We report herein the actinide-mediated insertion of E-H bonds (E = C, N, P, S) into various heterocumulenes including carbodiimides, isocyanates, and isothiocyanates. The precatalysts are prepared by a simple, one-pot procedure using readily available sta

Phosphine derivatives containing a P-H bond can add to the C=N double bond of a hetero-allene molecule RN=C=X.Ph2PH gives Ph2PC(X)NHR (X = O, S: R = Ph; X = N-p-tol: R = p-tol), cy-C6H11Ph2 gives cy-C6H11P2 (X = O, S) and Ph2P(Q)H gives Ph2P(Q)C
