AV502 Series – 720p HD Replacing Toshiba's AV500 series in the 26.0-inch, 31.5-inch and 37.0-inch (diagonal) sizes, Toshiba's new entry-level 720p LCD TV series offers high-gloss black cabinetry and a thinner bezel than its predecessor, plus two HDMI inputs and a PC input, creating a very feature rich entry-level lineup.
"Will I ever write again?" he asks in 1941, in the midst of his richest entries.
A number of electron-rich (entries 1 4), electron-neutral (entry 5), electron-deficient (entry 6), and ortho-substituted phenols (entry 7) efficiently coupled with benzoxazole to afford the products in excellent yields.
Electron-rich (entries 12, 13, 17 and 18), electron-poor (entry 16) and sterically hindered substrates (entries 12 and 14) could all be tolerated and products were isolated in good yields (79 93%) with low levels of diyne homo-coupling.
We conclude that barcode systems should either support richer data entry or continue to be supplemented with paper forms.
It was found that electron-rich halides (entries 1, 3, 4) upon coupling with benzo[ b]furan generally result in better yields than electron-deficient substrates.
Despite the rich price of entry, the firm has told clients it suspects the deal will be substantially oversubscribed.
There's no requirement for the content viewer to purchase Pixeom hardware or download their application, although there is a free mobile app for accessing the Pixeom Exchange Network of public content, as an alternative and richer point of entry to accessing this content via a web browser.
The reaction was tolerant of electron-poor aromatic substituents (Table 2, entries 6 and 9), an electron-rich aromatic substituent (entry 8) and an aryl bromide substituent (entry 7).
("Return to New York and suddenly feel the stark difference between rich and poor," one entry begins, in 1987).
