Preferred Definitions:    n = 3-5; and    Y1 = 5,5-dimethyl-1,3 dioxane.    SPECIFIC COMPOUNDS - 9 Compound (I) are specifically claimed e.g. 2-(5'-bromo-2,2'-bithien-5-yl)-5,5-dimethyl-1,3-dioxane, 5"-(5,5-diethyl-1,3-dioxan-2-yl)2,2':5',2"-terthiophene, tributyl(5"-(5,5-diethyl-1,3-dioxan-2-yl)-2,2':5',2"-terthien-5-yl)stannane of formula (Ia), 5"-(5,5-dimethyl-1,3-dioxan-2-yl)-2,2':5',2"-terthiophene-5-carbaldehyde and 5''''-(5,5-diethyl-1,3-dioxan-2-yl)-2,2':5',2':5'',2''':5''',2''''-quinquethiophene-5-carbaldehyde.    EXAMPLE - Solution of 5-formyl-2,2'-bithiophene (18 g) and sodium bicarbonate (8.4 g) was added in dry chloroform (160 ml) followed by adding bromine (15.57 g) in dry chloroform (84 ml) over a period of 1 hours. The reaction mixture was refluxed for 4 hours, cooled to room temperature and poured into cold water. A large volume of chloroform was added and the organic phase washed with a saturated aqueous solution of sodium bicarbonate. Upon drying on magnesium sulfate and evaporation of solvent, the crude product was recrystallized twice in toluene and rinsed with pentane to form 2-(5'-bromo-2,2'-bithien-5-yl)-5,5-dimethyl-1,3-dioxane.
