The Heck arylation of ethene with iodoarenes was investigated with a preformed [PdCl2(tppms)2] catalyst and gave the product styrenes in 60100% yield (115). In contrast, when the in situ system Pd(OAc)2 + 2tppms was used as a precursor, the conversion was less effective and yielded ...
The yield of C{sub 2}H{sub 4} formed during the reaction of C{sub 2}H{sub 5} with O{sub 2} has been determined at 298 K for pressures from 1.0 to 6,000 Torr. Ethyl radicals were formed by UV irradiation of mixtures of Cl{sub 2}, C{sub 2}H{sub 6}, O{sub 2}, and N...
The bond between 'Ga' and the dot represents the multiple bonds between the gallium ion and oxygen nuclei of the silica surface. Each reaction arrow is labeled with the electronic activation energy of the reaction in kJ mol−1. Barrierless reactions, both endo- and exothermic, are labeled ...
Fig. 1: Preparation and characterisation of a single-molecule catalyst device. a Schematic of a single-molecule device for the Mizoroki–Heck reaction. Black ball: carbon atom in graphene; brown ball: carbon atom in the molecular bridge; red ball: oxygen atom in the molecular bridge; dark blu...
The purpose of Experiment 6 - Part 1, was to use electrophile addition to synthesize 1,2‐dibromo‐1,2‐diphenylethane from (E)-1,2-diphenylethene. The final product was correctly identified by the use of TLC and melting point determination. The final product was meso-1,2‐dibromo‐1,2...
The triphenylmethyl radical reacts with a number of reagents, including oxygen to give the peroxide, iodine to give the iodide, nitric oxide to give the nitroso compound:Triphenylmethyl radicals couple to the Gomberg dimer, rather than the hexaphenyl ethane, Ph3C-CPh3, as Gomberg originally ...
