Oxidative Dephosphorylation of Benzylic Phosphonates with Dioxygen Generating Symmetrical trans-Stilbenes

Under a dioxygen atmosphere, benzylphosphonates and related phosphoryl compounds can readily produce the corresponding trans-stilbenes in high yields with high selectivity upon treatment with bases. Various functional groups were tolerable under the reaction conditions.

A highly stereoselective and efficient catalytic approach for the synthesis of trans-stilbene–arenes as π-conjugated materials

The potential expansion of the variety of catalytic methods for carbon–carbon bond formation is explored in many research centers all over the world. In this work, we describe very precise and controlled catalytic transformations as useful tools for the synthesis of new trans-π-conjugated molecular organic compounds. The combination of Suzuki–Miyaura coupling and cross-metathesis reactions is established as a simple and efficient method for the design of new (E)-stilbenes in the presence of well-defined transition-metal catalysts at 0.0001–1 % loadings. All of the desired products are isolated in good-to-excellent yields (up to 96 % isolated yield) with high purity.

A new efficient synthesis of the stilbenoid laser dyes BPS and Stilbene i by palladium-catalyzed coupling of ethene with bromoarenes

The palladium-catalyzed coupling of ethene with 4-bromobi phenyl and 4′-bromo-4-biphenylsulfonic acid permits a facile one-pot preparation of the laser dyes (E)-4,4′-diphenylstil bene (BPS, 3) and bis (trie thylammonium) (E)-4,4′-diphenyl-stilbene-4″,4?-disulfonate (6) in diastereomerically pure form on a multigram scale, with yields of 69 and 64%, repectively. The latter can easily be transformed to its dipotassium salt 7, the Stilbene I dye. VCH Verlagsgcscllschaft mbH,.
