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.

Synthesis of Substituted 1,4-Divinylbenzenes by Heck Reactions with Compressed Ethene

Substituted 1,4-divinylbenzenes 3a-i were synthesized by twofold Heck coupling from the corresponding 1,4-dibromo- (electron withdrawing substituents) or 1,4-diiododialkoxybenzenes 1a-i and ethene. Oligomerizations could be suppressed by increasing the pressure of ethene to 30 bar, simultaneously improving the yields of the title compounds.
