Title:
DIRECT SYNTHESIS OF DI-HETEROATOM CONTAINING CYCLIC ORGANIC COMPOUNDS
Document Type and Number:
WIPO Patent Application WO2005023793
Kind Code:
A3
Abstract:
The present invention provides for the simplified, direct synthesis of di-heteroatom containing cyclic organic compounds by forming an aqueous mixture of material of the formula (I); wherein X and Y are heteroatoms which may be the same or different and X is selected from the group consisting of 0, S and N, and both Y's are the same and are selected from the group consisting of 0, S and N, and R<1> through R<8> are the same or different and are selected from the group consisting of H, C1 to C10 alkyl radicals, C1 to C10 aryl radicals, C1 to C10 alkyl aryl radicals, and z is zero when X and Y are 0 or S, and z is 1 when X and Y are N, and water at a mole ratio of water to material of formula (I) in the range of about 10: 1 to about 0.001: 1 and heating the mixture to a temperature in the range of about 250°C to about 350°C under autogeneous pressure for a time of from about 0.5 to 10 hours. Trace amounts of liquid, solid or gaseous acid can be present to further accelerate dehydration, dehydrosulfurization or deamination and cyclization.
