The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: 1,3-Bis(2,4,6-trimethylphenyl)-1,3-dihydro-2H-imidazol-2-ylidene(SMILESS: CC1=CC(C)=CC(C)=C1[N+]2=[C-]N(C3=C(C)C=C(C)C=C3C)C=C2,cas:141556-42-5) is researched.HPLC of Formula: 148-51-6. The article 《Interaction between Spirosilanes and Lewis Bases: from Coordination to Frustration》 in relation to this compound, is published in Chemistry – A European Journal. Let’s take a look at the latest research on this compound (cas:141556-42-5).
In this work, the interaction between Lewis bases, especially N-heterocyclic carbenes (NHCs), and hindered neutral silicon derivatives featuring high Lewis acidity is described. The formation of normal and abnormal Lewis adducts could be controlled by varying the acidity of the corresponding tetravalent spiro organosilane. Some DFT calculations permitted to gain insight into the thermodn. of the NHC-spirosilane interaction featuring various NHCs differing in size and σ-donor capacity. Spirosilanes are introduced as new Lewis partners in frustrated Lewis pair (FLP) chem. and some FLP-type reactivities are presented, in particular the activation of formaldehyde that could occur with both hindered NHCs and phosphines.
From this literature《Interaction between Spirosilanes and Lewis Bases: from Coordination to Frustration》,we know some information about this compound(141556-42-5)Electric Literature of C21H24N2, but this is not all information, there are many literatures related to this compound(141556-42-5).
