To convert a pdf: Convert the first page of a PDF file with pdf2svg file.pdf file.svg. To extract all pages of a multiple-page PDF use pdf2svg file.pdf output-%02d.svg all. This generates output files output-00.svg, output-01.svg, etc. where the pattern "%02d" is replaced by the respective two-digit page numbers.
Select the page of the PDF you are interested in if the PDF is a multi-page document (Illustrator will only open one page at a time). Go to File > Save As (Shift + Ctrl + S). From the Format drop-down menu, select SVG (*.SVG). Save As. In the resulting dialog box: Under SVG Profiles, choose a profile (usually SVG 1.0 or SVG 1.1).

In chemistry, the hydrogenation of carbon–nitrogen double bonds is the addition of the elements of dihydrogen (H 2) across a carbon–nitrogen double bond, forming amines or amine derivatives. [1] Although a variety of general methods have been developed for the enantioselective hydrogenation of ketones, [ 2 ] methods for the hydrogenation of ...

The mechanism below begins with an O-acylated hydroxamic acid derivative that is treated with base to form an isocyanate that generates an amine and CO 2 gas in the presence of H 2 O. The hydroxamic acid derivative is first converted to its conjugate base by abstraction of a hydrogen by a base.
