Abstract

In the title compound, two tert-butyl groups replace the two hydrogen atoms at the C2 and C3 positions of the cyclohexadiene, respectively, and the electrophilic ester group replaces the hydrogen atom at the benzene ring position, as shown in the figure. Since all hydrogen atoms in this structure are not conformational isomers, * is used to distinguish all hydrogen atoms. [Extracted from the article]

Abstract

82 p. Renewable energy sources such as wind are intermittent and variable in nature. Hence, wind powered generators with variable-speeds can't connect to the grid directly. Small scaled wind generator, which directly couples to the grid with constant speed and constant power generated, has low efficiency and result in harmonics. Master of Science (Power Engineering)
