Title:
SYNTHESIS OF REDUCING AGENT PRECURSOR
Document Type and Number:
Japanese Patent JPS61100544
Kind Code:
A
Abstract:
A process for producing a quinone of the formula
wherein n is zero, 1 or 2; Y<1> is alkoxy; Y<2> is H, C1, Br or alkoxy; and R min and R sec are independently selected from H, alkyl and phenyl, which comprises the steps of:
(a) reacting a tetrabromide of the formula
with potassium iodide;
(b) reacting the product of step (a) with a 2-alkoxy-1,4-benzoquinone, to give the desired quinone when Y<2> is H;
(c) if desired, reacting the quinone in which Y<2> is H with C12 or Br2, to give the desired quinone in which Y<2> is C1 or Br; and
(d) if desired, reacting the quinone in which Y<2> is C1 or Br with a lithium, sodium or potassium alkoxide, to give the desired quinone in which Y<2> is alkoxy.
