Ethylene Insertion into a Ruthenium-Phenyl Bond of a Chiral Lewis Acid. A Facile Method of Preparing Olefin-Hydride Complexes. The Crystal Structure of [CyRuH(C2H3Ph)(PPh3)] SbF6.cntdot.CH2Cl2

Ruthenium-Catalyzed Oxidative Heck Reactions

“…Ruthenium complexes are readily accessible, but less widely utilized in the catalysis of C−C coupling reactions 4. Faller and Chase demonstrated that complex 1 b , prepared from the dichloride 1 a and PhMgBr, reacted with ethene and AgSbF 6 to form styrene and the corresponding Ru–H complex 2 5. An intramolecular variant through insertion of ethene into the Ru−C bond of complex 3 was reported by Pfeffer and co‐workers 6.…”

Ruthenium Complex-Catalysed Heck Reactions of Areneboronic Acids; Mechanism, Synthesis and Halide Tolerance

“…The first was due to Faller and Chase, as shown in Scheme 2. [15] The C À C bondforming step in their sequence is a clear model for ruthenium Heck chemistry. Thus, (p-cymene)(PPh 3 )RuCl 2 reacted with PhMgBr by single displacement.…”

Ruthenium-Catalyzed Oxidative Heck Reactions

“…[2,3] To the best of our knowledge, only one nonracemic double-helical molecule has been prepared. [5] The synthetic route is shown in Scheme 1. [4] However, this synthesis was rather lengthy, and only one enantiomer was obtained.…”

“…We report here on a rational synthesis and full characterization of double-helical alkynyl cyclophanes 1 of both enantiopure forms. [5] The synthetic route is shown in Scheme 1. Separately (R)and (S)-2,2'-diformyl-1,1'-binaphthyl (2) [6] underwent carbon ± carbon coupling, and the resulting diethynyl compound 3 was converted to the monosilylethynyl derivative 4.…”
