The data listed in Table-2 were selected bond lengths and bond angles of [Cu2L(pyridine
Synthesis of D in n-butanol with minor amounts of pyridine
.--The mixture was stirred into a 1,000-mL reactor where 180.0 g of urea, 450.0 g of butanol, and 4.0 g (0.73%) of pyridine
were added sequentially.
Rapid detection of pyridine
compounds by extractive atmospheric pressure chemical ionization mass spectrometry.
Table 2 presents data on the concentration of the Lewis acid sites because Bronsted centers capable of protonating pyridine
(region between 1530 and 1550 [cm.sup.-1] ([nu]CCN 19b)) have not been found.
In this paper, the amino acid fraction, obtained following the procedure described above and reported in the literature , is derivatized using anhydrous dimethylformamide instead of pyridine
were used as medical scaffolds because they are part of many natural product structures [10, 11].
From the biological activity investigation, we observed that the antitumor activity of compounds 1 and 2 advanced greatly when organic ligands pyridine
and Schiff bases were in coordination with Co ion.
The position of the methyl group relative to the imino nitrogen influences the catalytic activity of the 1,2-bis-benzoxazolyl benzene (41, 42), 1,2-bisbenzoxazolyl-4-methylbenzene (44, 45), 1,2-bisbenzoxazolyl-4-chlorobenzene (47, 48), 1,2-bis benzoxazolyl-4-bromobenzene (50, 51) and 2,6-bis benzoxazolyl pyridine
(66, 67) vanadium complexes, the methyl group in para position to the imino nitrogen (42, 45, 48, 51 and 67) increases the electron density on the metal atom and hence this is leading to a weaker interaction between the metal centre and the [pi]-electrons of ethylene resulting in a lower activity , (Figure 11).
The PLP pyridine
ring was well stacked with His114 and bound to Ala192 with van der Waals interaction at the opposite side (Figure 2(c)).

The alarm was raised after the worker dropped a one-litre glass bottle containing pyridine
on the staircase of the three-storey building sparking a three-hour clean-up and evacuation on Tuesday night.
