Method For Preparing Nitrogen Compounds

The present invention relates to a method for preparing nitrogen compounds using carbon dioxide, and to the use of the method in the production of vitamins, pharmaceutical products, adhesives, acrylic fibres, synthetic leathers, pesticides, herbicides, antifungal agents and fertilisers. The invention also relates to a method for producing vitamins, pharmaceutical products, adhesives, acrylic fibres, synthetic leathers, pesticides, herbicides, antifungal agents and fertilisers, which includes a step of preparing nitrogen compounds using the method of the invention. The invention further relates to a method for preparing labelled nitrogen compounds using carbon dioxide and to the uses thereof.

STUDIES ON 4-QUINAZOLINONES. PART IX. RANEY NICKEL DESULPHURISATION OF 4-THIOQUINAZOLINES: ALUMINA CATALYSED HYDRATION OF 1,4- AND 3,4-DIHYDROQUINAZOLINES

A number of 2-substituted 3,4-dihydroquinazolines and 1,2-disubstituted 1,4-dihydroquinazolines but not the 3-mono or 2,3-disubstituted derivatives, prepared by Raney nickel desulphurisation of the corresponding 4-thioquinazolines (IV), underwent unusual
