- Method for preparing 1,3-dioxane compounds
-
A method for preparing 1,3-dioxane compounds of the formula (I): STR1 wherein R1 and R2, independently of one another, represent hydrogen or a hydrocarbon radical; and X1 and X2, independently of one another, represent an electronegative groups, which method entails reacting a bis(hydroxymethyl) compound of the formula (II): STR2 in which X1 and X2 each, independently of one another, are as defined above, with an orthocarboxylic acid ester of the formula R4 --C(OR5)3 (III), in which R4 represents hydrogen or a hydrocarbon radical and R5 represents a hydrocarbon radical, and with an aldehyde or ketone of the formula R1 --CO--R2 (IV), in which R and R each, independently of one another, are as defined above.
