The present invention relates to a compound according to formula 1:suitable for use as a layer material for electronic devices, and to an organic semiconductor layer comprising at least one compound according to formula 1, as well as to an organic electronic device comprising at least one organic semiconductor layer, and a method of manufacturing the same.
Evaluation and development of methodologies for the synthesis of thiophosphinic acids

Thiophosphorus acids R1R2P(S)OH constitute an important class of organophosphorus compounds, in which the phosphorus atom is intrinsically chiral if R1 ≠ R2. In connection with a project aimed at the preparation of chiral thiophosphorus acids, various available literature methods were considered, but few fit the requirement of odorless reagents. Herein, the results of our studies on the synthesis of thiophosphinic acids are reported. Ultimately, two major approaches were selected: (1) the Stec reaction of phosphorus amides with carbon disulfide; and (2) the one-pot synthesis of thiophosphorus acids from H-phosphinates, an organometallic nucleophile, and quenching with elemental sulfur. An application to the preparation of a potential chiral phosphorus organocatalyst is also reported.

Catalytic synthesis of nonracemic P-chiral phosphine derivatives remains a significant challenge. Here we report Cu-catalyzed enantioselective arylation of secondary phosphine oxides with diaryliodonium salts for the synthesis of tertiary phosphine oxides
