摘要： A novel sulfoxide derivative of the general formula

WHEREIN R1 and R3 are the same or different, and each represents and alkyl group having 1 to 4 carbon atoms, a phenyl group or a halo- or methyl-substituted phenyl group, R2 is a hydrogen atom, a lower alkyl group, benzyl group, or a p-methoxy- or P-bromobenzyl group, R1 and R2, together, may form an alkylene group containing 3 carbon atoms, and X is an oxygen or sulfur atom, and to a process for its preparation.

摘要： 1. A METHOD OF PREPARING AN ALDEHYDE OF THE FORMULA

1-R1,2-R2,5-(H-CO-CH2-)-BENZENE

WHEREIN R1 IS A MEMBER SELECTED FROM THE GROUP CONSISTING OFF HYDROGEN AND ALKOXY HAVING 1 TO 4 CARBONS, R2 IS A MEMBER SELECTED ROM THE GROUP CONSISTING OF HYDROGEN, HALOGEN AND ALKOXY HAVING 1 TO 4 CARBONS, AND R1 AND R2 TOGETHER REPRESENT ALKYIDENEDIOXY HAVING 1 TO 4 CARBONS, WHICH COMPRISES THE STEPS OF SUBJECTING TO AN ACIDIC HYDROLYSIS A SULFOXIDE OF THE FORMULA

1-R1,2-R2,5-(R3-S(=O)-CH(-S-R3)-CH-CH2-)-BENZENE

WHREIN R1 AND R2 HAVE THE ABOVE MEANINGS, AND THE TWO R3 GROUPS ARE THE SAME AND EACH SELECTED FROM THE GROUP CONSISTING OF ALKYL HAVING 1 TO 4 CARBONS AND PHENYL SAID ACIDIC HYDROLYSIS BEING CARRIED OUT IN THE PRESENCE OF MINERAL OR ORGANIC PROTIC ACID HAVING A PK SMALLER THAN ABOUT 1 OR LEWIS AICDS.
