3,9-Di-2-furyl-2,4,8,10-tetra-oxa-spiro-[5.5]undecane
Abstract:
The title compound, C(15)H(16)O(6), was prepared by reaction of 2,2-bis-(hydroxy-meth-yl)propane-1,3-diol with 2-furaldehyde in the presence of hydro-chloric acid at room temperature. The asymmetric unit contains two crystallographically independent mol-ecules. In these two mol-ecules, the dihedral angles between the five-membered rings are 56.4 (3) and 56.3 (3)°. The six-membered rings adopt chair conformations. Inter-molecular C-H⋯π inter-actions link the mol-ecules and may be effective in the stabilization of the crystal structure.

SN2 Reaction: Kinetics
In a chemical reaction, a relationship exists between the concentration of reactants and the rate at which the reaction proceeds. The study to measure this relationship is known as the kinetics of a chemical reaction. Kinetic studies are used to deduce the rate law of a chemical reaction, which provides information about the species involved during the transition state of the rate-determining step. Thus, kinetic studies help to derive the mechanism of a...
SN2 Reaction: Mechanism
The presence of the more electronegative halogen in the substrate creates a polarized carbon-halide bond. The halide pulls the electron cloud generating an electrophilic center at the carbon atom. Thus, the carbon atom carries a partial positive charge while the halide has a...
SN2 Reaction: Transition State
When the nucleophile approaches the electrophilic carbon with its lone pairs, the halide acts as a leaving group and moves away with the electron-pair bonded to the carbon. Dotted partial bonds represent the bonds being formed or broken...
