Nevertheless, the transformation occurs readily because the highest occupied molecular orbitals (HOMO) of the starting materials are metal non-bonding orbitals and because the products are very stable with a WO multiple bond. Ale facile C O cleavage is not a general reaction of η2-aldehyde or ...
The law of conservation of mass states that matter cannot be created or destroyed, which means there must be the same number atoms at the end of a chemical reaction as at the beginning. To be balanced, every element in CH2CH2CH2 + HCl = CH2Cl2 + H2 must have the same number of ...
Treatment of hexachloropropene (Cl2C[double bond, length as m-dash]C(Cl)-CCl3) with Si2Cl6and [nBu4N]Cl (1:4:1) in CH2Cl2results in a quantitative conversion to the trisilylated, dichlorinated allyl anion salt [nBu4N][Cl2C[double bond, l... I Georg,M Bursch,B Endeward,... -...
Experimental and Theoretical Studies on the Conjugation of the PhosphorusCarbon Double Bond with a Cyclopropyl Group X-ray structural analysis for (Z)-2-cyclopropyl-1-(2,4,6-tri-tert-butylphenyl)-1-phosphaethene (2) was performed to confirm that the cyclopropyl group larg... S Kimura,S Ito...
The crystal structure of [Ru2{μ-CNMe2)(μ-CO)(COPh)(CO)(Cp)2] 2a reveals the double bond character of the μ-C N group and the interligand interaction involving the acyl oxygen and the μ-CNMe2 moiety. Type 2 complexes are also formed by reacting 1a–b with LiR′ (R′=Me, ...
In reagents containing the functional grouping I, a leaving group serves to mask a latent conjugated double bond that is not exposed until after the first alkylation has occurred to give a reagent including the functional grouping II and bis-alkylation results from sequential and interactive Michael...
It is found that the resonance between the π electrons on the CX double bond and the nitrogen lone pair significantly stabilizes the planar conformation in HCXNH2 (X = O, NH, CH2, S, and Se). The absolute resonance energy follows the order of formamide < thioformamide < selenoformamide...
Using a proton-nitrogen double resonance technique we have determined the quadrupole coupling of(14)N in the room temperature orthorhombic (Cmca), the low temperature tetragonal (P4(2)/ncm), and the monoclinic low temperature (P2(1)/c) p... M Mihailov,S Dirlikov,N Peeva,... - 《Die ...
The effects of chain length, separating the hydroxyl group and the CC double bond, in the Fe+- mediated CH/CC bond activation of CH3(CH2)m CH=CH(CH2)n OH has been studied. For n = 2-4, the dominant reactions involve exocyclic allylic CC bond cleavage of the chelate formed by intera...
The calculational results indicate that the initial step of the reaction consists of an attachment of the electrophilic O(3P) atom to both the carbon atoms of the double bond to form lower-energy intermediates IM1 and IM2. Among all these reaction channels the formation of CH2C(O)H+CH3 ...
