Pyrolysis of 2,2-diphenyl-2-methoxy derivatives of the title compounds in the gas phase gives phosphinates or phosphinamidates derived from the substrate by formal loss of methylene.Control experiments show that the reaction involves radical cleavage initiated by rupture of the oxazaphosph(V)ole ring.Pyrolysis of 3-aryl-2,2-dimethoxy-2-phenyl derivatives of the title compounds under similar conditions results in the formation of 3-aryl-2,3-dihydro-2-oxo-2-phenyl-1,3,2-benzoxazaphospholes.No significant products could be isolated from 2,2,2-trimethoxy derivatives, though vigorous conditions were required for their complete breakdown.The pyrolysis of the corresponding 2,2-diphenyl-2-ethoxy, 2,2-diethoxy-2-phenyl, and 2,2,2-triethoxy compounds gave higher yields of similar products, possibly via a six-centre concerted elimination.

Cobalt has become increasingly attractive in homogeneous catalysis because of its unique characteristics and outstanding catalytic performance in addition to being cheap and earth-abundant. Hydride transfer processes are involved in a broad range of organic transformations that allow the facile preparation of various useful chemicals and synthetic building blocks. These reactions have continuously received great attention both from academia and industry. In this perspective, we review homogeneous cobalt-catalyzed hydride transfer reactions according to the classified reaction types and provide a comprehensive overview of the design, synthesis, and reactivity of cobalt catalysts, their catalytic applications, and reaction mechanisms.

Future application of conjugated (co)polymers, e.g. in electronic devices, requires the availability of up-scalable synthetic procedures. “Conventional” (hetero)aryl-(hetero)aryl coupling schemes often produce toxic or environmentally risky by-products. Here, so-called direct arylation schemes without use of organometallic reagents or related anion equivalents came in the focus of attention as simplified alternative to standard coupling procedures. Now, a couple of structurally defined conjugated (co)polymers can be generated in high yield and molecular weight via direct arylation polycondensation. The promising application potential of these materials as active component of organic solar cells has been demonstrated.

On the basis of mechanism-driven reaction design, a Pd-catalyzed nucleophilic fluorination of aryl bromides and iodides has been developed. The method exhibits a broad substrate scope, especially with respect to nitrogen-containing heteroaryl bromides, and proceeds with minimal formation of the corresponding reduction products. A facilitated ligand modification process was shown to be critical to the success of the reaction.

This review highlights the use of a bisphosphine ligand group in homogeneous catalysis. This ligand group is known as the Xantphos-like ligands, which are based on the generic formula of 2,2?-bis(phosphino)diaryl ether. The synthesis of the main members is summarized and emphasis is given to ligands that can be easily synthesized, also on large scale. The catalytic applications are not comprehensively presented, but instead, about 20% of the examples from literature have been extracted, aiming at the demonstration of diversity, peculiar examples, historical development, design vs. trial and error, and new reactions. Metals ranging from group 7 to 11 have been used in a wide variety of reactions: hydroformylation, alkoxycarbonylation, hydrocyanation, cross-coupling reactions for many C-C and C-X bond forming reactions, carbonylative coupling reactions, phosphinations, etc.

The Pschorr cyclization of various arylamines with t-butyl thionitrate under nonaqueous conditions gave the corresponding cyclic products in moderate yields.The same reaction was also found to proceed readily with p-toluenesulfonyl nitrite at room tempoerature.Treatment of o-aminophenyl allyl ether or sulfide with t-butyl thionitrate resulted in the intramolecular Meerwein arylation to the olefinic bond affording 3-chlorochroman or – thiochroman, through the yield was low.The plausible mechanism of the Pschorr cyclization with t-butyl thionitrate is discussed.

Transesterification of phenylboronic and p-phenylenediboronic esters with phosphorus-containing polyols prepared by phosphine reactions with aldehydes leads to compounds containing two or more 1,3,2,5-dioxaboraphosphorinane rings linked together in various ways. The steric structure and reactivity of oligomeric 1,3,2,5-dioxaboraphosphorinanes are similar to those of mono- and di-1,3,2,5-dioxaboraphosphorinanes and controlled by np-sigma*C-O orbital coupling.
