DFT calculations predict the existence of three stable conformations (one opened and two closed conformations) of the new class of nucleoside with various substituents (X = H, CH3, F, Cl, and Br). The calculations predict also that the two closed con

X3Al-YC4H4 (X = H, F, Cl and Br; Y = O in furan, Y=NH in pyrrole, and Y = S in thiophen) have been investigated as donor−acceptor complex types using the DFT level of theory. Both staggered and eclipsed conformations have been examined. For all com

International audience; Highly diastereoselective 1,3-dipolar cycloaddition of in situ generated C,N-diaryl nitrilimines to (1R)-thiocamphor leads to chiral spiro-1,3,4-thiadiazolocamphane derivatives in good yields. The structures and stereochemistr

The reaction mechanism between AlX and HX (X = Br, Cl, and F) have been characterized in detail using DFT as well as the ab initio method. The reaction yielding AlX3 and molecular hydrogen was calculated to be highly exothermic. The present calculati

The complexation energies of H3BNHnCl3−n (n= 3-0) complexes and the proton affinities of NHnCl3−n compounds have been computed at the G2(MP2) level of theory. G2(MP2) results show that the successive chlorine substitution on the ammonia decreases

The mechanisms for the reactions of AlF with HCl have been characterized in detail using DFT as well as the ab initio method, including zero-point corrections. From the potential energy profile it can be predicted that the reaction process of forming

An ab initio computational study of the properties of the dihydrogen-bonded complexes of H 2 − n X n AlH ( n = 0–2; X = F, Cl) with the rare gas (Rg) compounds HArF and HKrF was carried out at the MP2(full)/6-311++G(2d,2p) level of theory. For al

Structures of protonated alane-Lewis base donor-acceptor complexes H2X2AlNHn(CH3)(3-n)+ (X = F, Cl, and Br; n = 0-3) as well as their neutral parents were investigated. All the monocations H2X2AlNHn(CH3)(3-n)+ are Al-H protonated involving hypercoord
