The fraction obtained by tituration using acetone as solvent contain alcohol, amides, alkynes, nitro group and amines.
In this context the Cu(I) catalyzed 1,3 dipolar cycloaddition of alkynes and azides has gained enormous popularity for its ability to dramatically increase the reaction rate and other beneficial effects such as high selectivity, reliability, an almost complete conversion, tolerance toward a wide range of functional groups etc.
Different from biodiesel and bioethanol, biooils are produced from pyrolysis of LCBM, resulting in dark brown oily liquid with extremely complex compositions, including water and hundreds of organic species which can be classified into hydrocarbons (alkanes, alkenes, alkynes, and aromatics), oxygen-containing species (ethers, alcohols, phenols, aldehydes, ketones, furans, esters, and carboxylic acids), and other heteroatomic organic compounds [21].
On the other hand, the hydroamination (HA) of alkynes catalyzed by transition metal complexes is an important reaction, which involves the C-N bond formation.
leaf extract and their catalytic activity for the Huisgen [3 + 2] cycloaddition of azides and alkynes at room temperature.
However, noticeable changes were observed after 6 months of application where the C-O stretching of phenolic OH (1400-1410 cm-1) was not detected in all treatments Meanwhile, C=C substance alkynes (2167 and 2202 cm-1) appeared at the 6th and 12th month, respectively, for raw RPMS treatment, which might be due to the influence of the raw RPMS composition.
At the peak of 2345.44 [cm.sup.-1], the broad bonding was being shown by the alkynes group of C=C stretching.
