A fast-response, highly sensitive and selective fluorescent probe with the 2-(diphenylphosphino)benzoate moiety as a recognition receptor for the ratiometric imaging of nitroxyl in living cells was first developed.

A nanoscopic pseudorotaxane (1)2 subset2 composed of the gold rectangle [Au4(mu-PAnP)2(mu-bipy)2](OTf)4 and the linear template 4,4'-bis(9''-anthryl)biphenyl was assembled (PAnP = 9,10-bis(diphenylphosphino)anthracene); bipy = 4,4'-bipyridine).

A tetranuclear molecular rectangle consisting of two bridging dicarbene ligands and two bridging diphosphine ligands was prepared by connection of two dinuclear gold(I) complexes with 1,2-bis(diphenylphosphino)ethane.

A new bicyclization strategy has been established, allowing a flexible and practical approach to 33 examples of pyrazolo[3,4-c]quinolines from low-cost and readily accessible triethylammonium thiolates with hydrazines. Notably, the features of this work include broad functional group compatibility, mild reaction conditions and good reaction yields.

Short phosphorothioate oligonucleotides have been prepared by refluxing an equimolar mixture of thymidine and triethylammonium phosphite in toluene in the presence of elemental sulfur. Desulfurization and subsequent digestion of the products by P1 nuclease revealed that nearly 80% of the internucleosidic linkages thus formed were of the canonical 3´,5´-type.

Chiral monophosphines (MOPs), whose chirality is due to biaryl axial chirality, are prepared from enantiometrically pure 2,2%-dihydroxy-1,1%-binaphthyl and 3,3%-dihydroxy-4,4%-biphenanthryl. The representatives are 2-(diphenylphosphino)-2%-methoxy1,1%-binaphthyl (MeO–MOP and 3-(diphenylphosphino)-3%-methoxy-4,4%-biphenanthryl (MOP–phen). The palladium complexes coordinated with the MOP ligands ...
