Using classical diazotisation of anilines, 5-(4-aminophenyl)-10,15,20-triphenyl-porphyrin was converted to a series of meso-tetraarylporphyrins with different substituents, including 5-(4-hydroxylphenyl)-10,15,20-triphenylporphyrin (80%), 5-(4-chlorophenyl)-10,15,20-triphenylporphyrin (74%), 5-(4-iodinphenyl)-10,15,20-triphenylporphyrin (76%), 5-(4-hydrazinephenyl)-10,15,20-triphenylporphyrin (67%) and 5-(4-bisphenyl)-10,15,20-triphenylporphyrin (32%). Therefore an efficient way of synthesizing unsymmetrically substituted TAPs was developed.

ChapterⅠintroduces the intention, significance and methods of the research from the angle of Chinese historical phonetics. Following the course of re-examining materials, ChapterⅡsurveys the pattern of rhyme, excerpting the metrical feet, ChapterⅢconnects the rhyme categories, the rhyme of different systems contacting with each other, and literary reading and colloquial reading. ChapterⅣcompares the rhyme cateories of traditional Hua-gu opera in Changsha with traditional rhyme tablesd, as well as those of traditional Hua-gu opera in Shaoyang. The total study is conducted to become united with dialect. ChapterⅤcontains the surplus discussion with three theories: the rhyming quality, the connection between rhyme categories and oral speech, between those of literary readings in traditional Hua-gu opera.

The 35-year-old midfield player has scored 147 times for Manchester United and the pick of the bunch was an incredible solo effort that started with him pouncing on a loose pass by Patrick Vieira in his own half and ended with him wheeling away in delight with his white shirt swirling above his head after he had slalomed his way through the Arsenal defence and slammed the ball past David Seaman.
