Abstract: Synthesis use of a new class of diaryliodonium salt photo and thermal polymerization initiators in which the aryl groups are substituted with alkoxy group bearing hydroxy groups. Good to excellent yields are obtained of diaryliodonium salts in which the aryl groups are substituted with long chain alkoxy groups, which alkoxy groups also possess at least one hydroxyl moiety attached at the 2-position of an alkoxy group. The resultant salts have enhanced solubility when compared with their lower molecular weight counterparts. The hydroxyl groups serve as chain transfer agents; and, in cross linking UV-induced cationic polymerizations, the hydroxyl groups effect marked accelertion on polymerization rates. The salts also have excellent compatability with nonpolar monomers such as epoxidized oil and poly(1,2-butadience oxide) and provide further benefits when they are used along with copper cocatalysts in thermally curable polymer systems.

Abstract: The invention includes a process wherein an olefin is carbonylated with carbon monoxide to form carboxylic acid esters in the presence of a catalyst complex of one mole of BF.sub.3 and one mole of alcohol, and the catalyst is recovered from the desired reaction product and the reaction by-products and is recycled. The carbonylation is carried out until approximately one-half of the alcohol is consumed to form a reaction mass containing the BF.sub.3, the alcohol, and carboxylic acid esters in a 2:1:1 molar ratio. In the first step, the one mole of free BF.sub.3 is vaporized from the reaction mass. The remaining admixture is a 1:1:1 mixture of the aforesaid compounds. To this mixture additional alcohol is added and the mixture is subjected to distillation. An azeotrope of the product carboxylic acid ester and the alcohol and residual alcohol are removed by the distillation, leaving a residue containing a 1:2 BF.sub.

Abstract: The novel borane-1,4-thioxane is synthesized by adding the calculated quantity of diborane to 1,4-thioxane. It is a stable liquid at 25.degree. C. The neat liquid is approximately 8.0 M in borane. The product, in spite of the additional oxygen atom in the ring, exhibits the desirable hydroborating and reducing action of borane-methyl sulfide. However, it possesses a major advantage over the latter in that the donor component, 1,4-thioxane, in contrast to methyl sulfide, is readily soluble in water and can be washed out of typical reaction mixtures. This greatly facilitates the synthetic applications of borane-1,4-thioxane over borane-methyl sulfide.
