A novel and efficient route to (E)-alk-1-enyl boronic acid derivatives from (E)-1-(trimethylsilyl)alk-1-enes and a formal Suzuki–Miyaura cross-coupling reaction starting with vinylsilanes
Representative aryl, vinyl and alkynyl bromides undergo efficient Pd-catalyzed cross coupling with trans-1-(9-borabicyclo[3.3.1]non-9-yl)-2-(trimethylsilyl)ethene (1) under basic conditions to produce the corresponding trans styryl-, dienyl- and enynylsilanes (58–89%).

efficient trans-selective hydrogenation of alkynes under lowhydrogenpressure and lowreaction temperatures is reported, applying a commercially available ruthenium hydride complex. The developed reaction conditions, which tolerate a variety of functional groups, are carried out in a two-chamber setup with ex situ generated hydrogen. The reaction setup is highly suitable for deuterium labeling. The trans-selective

A novel and highly efficient conversion of vinylsilanes into vinyl boronates is described together with their SuzukiâMiyaura cross-coupling reaction, performed without isolating the intermediate resulting from borodesllyiation.
