Abstract:
A process for preparing polyfunctional methylene-bridged compounds is disclosed. A difunctional methylene-bridged compound having acidic protons and having the formula X--CH.sub.2 --X is reacted with an alkali metal in the presence of a disubstituted formamide to provide a methylene-bridged polyfunctional compound having the formula ##STR1## wherein X is an electron-withdrawing group such as --CONH.sub.2, --COOR or --SO.sub.2 R where R is alkyl. The polyfunctional compounds prepared by the process of the present invention are useful in the production of metal complexing or sequestering agents, acidulents, cross-linking agents for polymeric reactions and in applications where a polyfunctional compound is desirably employed.
Abstract:
A novel method for producing hydroquinone and quinone derivatives by a regio- and stereo-specific coupling reaction of hydroquinone derivative having a terminal activated (poly)prenyl side chain with a prenyl derivative. This method can provide in good yield various hydroquinone and quinone derivatives having any prenyl length of the side chain.

Abstract:
A METHOD OF PREPARING DIMETHYLSULPHOXIDE BY OXIDIZING DIMETHYL SULPHIDE BY HIGH CONCENTRATED (70-100%) SOLUTIONS OF ORGANIC HYDROPEROXIDES E.G. ISOPROPYLBENZENEHYDROPEROXIDE OR ETHYLBENZENE HYDROPEROXIDE. THE PROCESS IS CARRIED OUT AT TEMPERATURES OF 20* -80* C. IN A TWOPHASE SYSTEM; THE FIRST PHASE IS AN AQUEOUS SOLUTION (1-8 MOLES H2O/MOL DMS) WITH AN ACID REACTION IN WHICH THE HYDROGEN ION CONCENTRATION IS FROM 10-6 TO 1 G./DM.3 SOLUTION, WHILE THE SECOND PHASE IS AN ORGANIC PHASE. EXTRACTION OF DIMETHYLSUPHOXIDE FROM THE REACTION SOLUTION IS EFFECTED BY THE AQUEOUS PHASE AND ANY REMAINING DIMETHYLSULPHOXIDE IN THE ORGANIC PHASE IS OBTAINED BY MEANS OF WASHING WITH AN AQUEOUS SOLUTION OF THE SAME HYDROGEN ION CONCENTRATION AS BEFORE. THE EXTRACTS ARE DISTILLATED UNDER REDUCED PRESSURE GIVING PURE DIMETHYLSULPHOXIDE. THE RAFFINATE IS A READY PRODUCT OR CAN SERVE AS A RAW MATERIAL FOR FURTHER SYNTHESES.
