Demchuk, Oleg M. published the artcileRational design of novel ligands for environmentally benign cross-coupling reactions, Formula: C22H18O2, the publication is Pure and Applied Chemistry (2011), 83(3), 633-644, database is CAplus.

Transition-metal (TM) complexes of new phosphines, readily prepared by a straightforward three-step modular synthesis, were successfully employed in difficult cross-coupling reactions conducted under mild conditions (water, “open-flask”, low temperature) that aspire to meet green chem. criteria. High yielding catalyzed by bismuth or rhodium complexes oxidative arylation of naphthoquinone gave the key 2-aryl naphthoquinone intermediates for facile bismuth triflate-catalyzed Michael addition of secondary phosphine oxides. Subsequent O-methylation and reductions of the resulting products gave access to the target air-stable phosphine ligands in good overall yields (up to 60%).

Briza, Tomas published the artcileChromophoric Binaphthyl Derivatives, Application of 2,2′-Dimethoxy-1,1′-binaphthalene, the publication is Organic Letters (2005), 7(17), 3661-3664, database is CAplus and MEDLINE.

A short synthetic route is outlined, starting from bromobinaphthyl derivatives, via halogen lithium exchange, subsequent Michael reaction with dimethylaminoacrolein, hydrolysis to the corresponding aldehyde, and final condensation with a benzothiazolium unit to produce a binaphthyl-pentamethinium system, which absorbs in the visible range around 450 nm. Enantiopure ligands show a good Cotton effect in the CD spectrum. Preliminary data show potential of these compounds in the area of supramol. chem. (enantioselective recognition) and also for medicinal application (induction of apoptosis).

Masuya, Yoshihiro published the artcileThiolate-Initiated Synthesis of Dibenzothiophenes from 2,2′-Bis(methylthio)-1,1′-Biaryl Derivatives through Cleavage of Two Carbon-Sulfur Bonds, Category: naphthyridine, the publication is Synlett (2019), 30(17), 1995-1999, database is CAplus.

Thiolate-initiated synthesis of dibenzothiophenes from 2,2′-bis(methylthio)-1,1′-biaryl derivatives through cleavage of two carbon-sulfur bonds was developed. This reaction did not require a transition-metal catalyst and was promoted by a thiolate anion. Notably, based on DFT calculations, the product-forming cyclization step was shown to proceed through a concerted nucleophilic aromatic substitution (CS_NAr) mechanism. Furthermore, this metathesis protocol enabled the method to be expanded to double carbon-oxygen bonds and carbon-oxygen/carbon-sulfur metathesis.
