The key developments in the chemistry of R2PBR’2 over the last 20 years are reviewed. The categorization of phosphinoboranes as R2PBR’2 species and borylphosphines as R2PBR’2 species is suggested based on an analysis of the literature X-ray crystal structures. The chemistry of derivatives of the simplest borylphosphine H2PBH2 is discussed. Six methods of preparation of R2PBR’2 are presented along with the reactions of the products with H2, amine-boranes, elemental chalcogens, Me3NO and compounds featuring CO, CC and CN functionalities.

An efficient protocol for Pd-catalyzed 2,2,2-trifluoroethoxylation of activated aryl bromides and bromo-chalcones has been developed. We unveil a fascinating insight into the Pd-catalyzed C-O cross-coupling reaction. Pd/tBuXPhos (L1) ligand system facilitates the C-O cross-coupling reaction between 2,2,2-trifluoroethanol and activated aryl bromides at both higher (115 C) and lower temperatures (40 C). Unprecedentedly, this catalyst system facilitates the C-O cross-coupling reaction in short span of reaction times, generally 5-25 min (at 115 C). The structurally simple analogue of tBuXPhos ligand so called JohnPhos (L2) ligand is also facilitated the C-O bond formation with activated aryl bromides and bromo-chalcones. Interestingly, under the optimal conditions (L1), methanol is also coupled rapidly with activated aryl bromides. These catalyst systems (L1 and L2) fail to couple electron rich aryl bromides with 2,2,2-trifluoroethanol, thus these catalyst systems allow the reductive elimination through an electronic pathway of reductive elimination. The unusual reactivity of 2,2,2-trifluoroethanol in Pd-catalyzed C-O cross-coupling reaction makes that the chemistry of fluorinated molecules is unique than that of non-fluorinated analogues. The bromo-chalcones can be used as a new coupling partner in the cross-coupling reaction.

We report the synthesis of air-stable Pd(i) dimer complexes featuring biaryl phosphine ligands. Catalytic experiments suggest that these complexes are competent precatalysts that can mediate cross-coupling amination reactions between aryl halides with both aliphatic and aromatic amine nucleophiles. This work represents an expansion of the air-stable precatalyst toolbox for Pd-catalyzed cross-coupling transformations.

The algorithmic, large-scale use and analysis of reaction databases such as Reaxys is currently hindered by the absence of widely adopted standards for publishing reaction data in machine readable formats. Crucial data such as yields of all products or stoichiometry are frequently not explicitly stated in the published papers and, hence, not reported in the database entry for those reactions, limiting their usefulness for algorithmic analysis. This paper presents a possible extension to the IUPAC RInChI standard via an auxiliary layer, termed ProcAuxInfo, which is a standardised, extensible form in which to report certain key reaction parameters such as declaration of all products and reactants as well as auxiliaries known in the reaction, reaction stoichiometry, amounts of substances used, conversion, yield and operating conditions. The standard is demonstrated via creation of the RInChI including the ProcAuxInfo layer based on three published reactions and demonstrates accurate data recoverability via reverse translation of the created strings. Implementation of this or another method of reporting process data by the publishing community would ensure that databases, such as Reaxys, would be able to abstract crucial data for big data analysis of their contents.

Anionic! Novel chiral anion catalysis of the enantioselective 1,4-reduction of the 1-benzopyrylium ion by a chiral phosphoric acid was accomplished with a Hantzsch ester as the reducing agent. The enantioselective reduction established is composed of a two-step consecutive transformation involving stereoablative loss of the hydroxy group from racemic 2H-chromen-2-ol derivatives to generate the achiral 1-benzopyrylium ion as a reactive key intermediate.
