Palladium nanoparticles ligated with inexpensive triphenylphosphine and amphiphile PS-750-M are suitable for exploring the reactivity of carbenes in aqueous nanomicelles. Nanocatalyst is highly selective for metal-carbene migratory insertion, and micelle
Solid phase synthesizing method of dihydronaphthalene compound

Paragraph 0051, (2016/10/10)
A solid phase synthesizing method of a dihydronaphthalene compound I belongs to the field of organic chemistry and comprises: 1, using 1% crosslinked polystyrene resin as a carrier to prepare a polystyrene-loaded selenium base succinimide reagent III; 2, under catalyzing of fluoroform sulfonic acid trimethyl estersil, using the III to induce olefin V to be subjected to intramolecular cyclization to form 3-polystyrene-loaded selenium base-1,2,3,4-tetrahydronaphthalene VI; 3, removing VI by an oxidant through oxidation without further separating, thereby directly obtaining dihydronaphthalene I. Raw materials are easy to obtain, the product yield is good, the purity is high, the operation is simple and convenient, the posttreatment is simple and the method has well industrial application prospect.

Air-stable P-chiral dihydrobenzooxaphosphole oxazoline ligands were designed and synthesized. When they were used in the iridium-catalyzed asymmetric hydrogenation of unfunctionalized 1-aryl-3,4-dihydronaphthalenes under one atmosphere pressure of H2, up to 99:1 e.r. was obtained. High enantioselectivities were also observed in the reduction of the exocyclic imine derivatives of 1-tetralones.
Atom-efficient vinylic arylations with triarylbismuths as substoichiometric multicoupling reagents under palladium catalysis
Rao, Maddali L.N.,Jadhav, Deepak N.,Venkatesh, Varadhachari
experimental part, p. 4300 - 4306 (2011/02/24)
The first atom-efficient arylation of vinylic iodides was achieved by using triarylbismuths as substoichiometric multicoupling reagents under palladium catalysis. Vinylic iodides were efficiently coupled with electronically divergent triarylbismuths to furnish the corresponding arylated products in short reaction times.
Dynamic kinetic resolution-asymmetric transfer hydrogenation of 1-aryl-substituted cyclic ketones

, p. 2485 - 2490 (2007/10/03)
A range of 1-aryl-2-tetranols, and 1-phenyl-2-indanol, have been generated in high yield and enantiomeric excess from the corresponding racemic ketones, via a dynamic kinetic resolution-transfer hydrogenation process, using Ru(II)-TsDPEN in formic acid/triethylamine (5:2). This provides a potential entry to an asymmetric total synthesis of benzazepines such as Sch 39166.
