标题:Synthesis of stable, water-soluble chemiluminescent 1,2-dioxetanes and intermediates therefor
发明人：BRONSTEIN IRENA Y; EDWARDS BROOKS
权利人:TROPIX INC
摘要:A novel synthesis of 1,2-dioxetane phosphate alkali metal salts and novel intermediates employed in this synthesis are disclosed. A hydroxyaryl enol ether alkali metal salt having the formula: ##STR1## wherein T can be an unsubstituted or substituted adamant-2'-ylidene group, R 3 can be a methyl group, Y can be a phenyl group and M + can be a sodium cation, is reacted with a phosphorohalidate to give the corresponding enol ether ethylene phosphate, which is then reacted with an alkali metal cyanide to give the corresponding enol ether cyanoethyl phosphate diester alkali metal salt intermediate. Singlet oxygen addition to this enol ether cyanoethyl phosphate diester alkali metal salt intermediate to give the corresponding 1,2-dioxetane cyanoethyl phosphate diester alkali metal salt, followed by β-elimination of the cyanoethyl group using an alkali metal hydroxide or the like, gives the corresponding 1,2-dioxetane phosphate alkali metal salt.

摘要:A method of preparing a fine particle iron based hydrocracking catalyst and the catalyst prepared thereby. An iron (III) oxide powder and elemental sulfur are reacted with a liquid hydrogen donor having a hydroaromatic structure present in the range of from about 5 to about 50 times the weight of iron (III) oxide at a temperature in the range of from about 180° C. to about 240° C. for a time in the range of from about 0 to about 8 hours. Various specific hydrogen donors are disclosed. The catalysts are active at low temperature (<350° C.) and low pressure.

摘要:Microwave heating is used to synthesize NHC-transition metal complexes. Reaction times for the formation of NHC-transition metal complexes is greatly reduced. The speed of the reactions allows for otherwise problematic air handling of reagents. Apparatus for carrying out the reactions is less complex than conventional apparatus and requires less energy to achieve the desired temperatures. Methods utilize salts of NHC's which overcomes the oftentimes difficult preparation of free carbenes for formation of the corresponding transition metal complexes.
