چکیده
efficient cyclization upon irradiation in acetonitrile to produce the spirocyclic enol ethers or esters 56-59. The ease of formation of the salts coupled with the exceptional chemical efficiencies and structural outcomes of these cyclizations indicates that this methodology will have synthetic utility. The results also demonstrate the importance of trialkylsilyl substituents in electrontransfer photochemical studies both as mechanistic probes and as groups to control reaction efficiency and regiochemistry.

Development of a New Force Field for Polynorbornene
A new force field has been customized for the variation of polynorbornene that contains a bicycloheptane group in the backbone structure. The force field was developed from ab initio density functional theory (DFT), and semiempirical electronic structure calculations for both stereochemical dimers of the 2,3 exoexo isomer of polynorbornene. The bond length and bond angle parameters were determi...
متن کاملNuclear Quadrupole Interactions in Cadmium Complexes: Semiempirical and ab initio Calculations
Z. Naturforsch. 54 a, 422-430 (1999); received March 29, 1999 Semiempirical calculations, based on the so-called angular overlap model, have been compared with ab initio methods (MP2) for the calculation of nuclear quadrupole interactions (NQPs) in cadmium complexes with biologically relevant ligands (H2O, O H , cysteinate, carboxylate, and imidazole). The assumptions on which the semiempirical...
متن کاملGlobal Optimization of SixHy at the Ab Initio Level via an Iteratively Parametrized Semiempirical Method
Previously we searched for the ab initio global minima of several SixHy clusters by a genetic algorithm in which we used the AM1 semiempirical method to facilitate a rapid energy calculation for the many different cluster geometries explored. However, we found that the AM1 energy ranking significantly differs from the ab initio energy ranking. To better guarantee locating the ab initio global m...
متن کاملImprovement of DNA and RNA Sugar Pucker Profiles from Semiempirical Quantum Methods
Neglect of diatomic differential overlap (NDDO) and self-consistent density-functional tight-binding (SCC-DFTB) semiempirical models commonly employed in combined quantum mechanical/molecular mechanical simulations fail to adequately describe the deoxyribose and ribose sugar ring puckers. This failure limits the application of these methods to RNA and DNA systems. In this work, we provide bench...
متن کاملSemiempirical van der Waals interactions versus ab initio nonlocal correlation effects in the thiophene-Cu(111) system
The adsorption mechanism of single thiophene (C4H4S), 4-thiophene (C16H10S4), and their dimers on the Cu(111) surface has been studied in the framework of the density functional theory (DFT). The importance of the London dispersion effects on the molecule-surface adsorption geometry and the corresponding binding energy was investigated by using semiempirical and first-principles methods.
