Reactions of Organoaluminium Compounds with Electron Donors
The application of organoaluminium compounds as components of organometallic or complex systems is connected with a knowledge of their reactions with electron donors. Reactions with nitriles, ketones, esters, ethers, alkyl chlorides, vinyl chloride, and acid chlorides as the electron donors were investigated. The first stage of the reaction of an organoaluminium compound with an electron donor ...
متن کاملPhysical Triplet Quenching by Electron Donors
Absolute radical yields, as determined by flash spectroscopy, are reported for the reaction of the thionine triplet 3TH+ and its protonated form 3TH2++ with a variety of electron donors in methanolic solution. The different yields, extrapolated to infinite donor concentrations, are due to partial physical quenching of the triplets in the electron transfer reaction. The results are indicative of...
متن کاملHybrid super electron donors – preparation and reactivity
Neutral organic electron donors, featuring pyridinylidene-imidazolylidene, pyridinylidene-benzimidazolylidene and imidazolylidene-benzimidazolylidene linkages are reported. The pyridinylidene-benzimidazolylidene and imidazolylidene-benzimidazolylidene hybrid systems were designed to be the first super electron donors to convert iodoarenes to aryl radicals at room temperature, and indeed both sh...
متن کاملQuantum Computation with Electron Spins of Phosphorous Donors in Silicon
The discovery of efficient quantum algorithms a decade ago has shown that a quantum computer encoding and processing information quantum mechanically, can solve important problems intractable with conventional computers. The invention of quantum error correction principle, makes quantum computation possibly fault-tolerant against the decoherence of information carriers. Thereafter, intensive re...
متن کاملElectron Spin Coherence of Phosphorus Donors in Isotopically Purified Si
We investigate spin coherence time of electrons bound to phosphorus donors in silicon single crystals, employing a pulsed electron paramagnetic resonance technique. The samples were isotopically controlled so that they may possess different concentrations (about 5% and 100%) of 29Si, which is the only non-zero-spin (spin-1/2) stable isotope of Si. Both 29Siconcentration dependence and orientati...
