Synthesis of Unsaturated Starburst Compounds with a Boron Atom in the Core
摘要:
A highly effective method for regio- and stereoselective synthesis of unsaturated starburst compounds with a boron atom core and a trans configuration of all double bonds via silylative coupling of selected olefins (styrenes, vinylboronates, and vinylsilanes) with boron tris-(dimethylvinylsiloxide) catalyzed by [Ru(CO)ClH(PCy3)(2)] is described. All products could be potential precursors for new highly branched materials with unique mechanical, thermal, and optoelectronic properties.

The catalytic activity of the pentamethylcyclopentadienylsilicon(II) cation Cp*Si:+ was investigated. It was shown that Cp*Si:+ efficiently catalyzes reactions of technical relevance in organosiliconchemistry: Cp*Si:+ proved to be a very efficient nonmetallic catalyst for the hydrosilylation of olefins at low catalyst amounts of <0.01 mol % and for the Piers–Rubinsztajn reaction in order to make controlled
