Abstract: The fluorine content of an acyclic saturated compound of the formula C.sub.n F.sub.a X.sub.b H.sub.c (wherein each X is independently selected from the group consisting of Cl and Br, and wherein n is 1 to 6, a is 1 to 13, b is 0 to 12, c is 1 to 9, and a+b+c equals 2n+2) is reduced by reacting the acyclic saturated compound with HCl in the vapor phase at an elevated temperature in the presence of a catalyst, the mole ratio of HCl to the acyclic saturated compound being at least about 1:1.

Abstract: A process for producing sulfuryl chloride and/or thionyl chloride is disclosed which involves contacting a mixture comprising SO.sub.2 and Cl.sub.2 (e.g., at about 300.degree. C. or less) with a silicon carbide catalyst having a surface area of at least 10 m.sup.2 .multidot.g.sup.-1.

Abstract: Transition metal compounds of the formulaeM.sup.1 A.sub.3 (1)whereinM.sup.1 is scandium, yttrium, chromium, or rare earth metal, andA is 2-dialkylaminobenzyl or 2-dialkylaminomethylphenyl, or a lower alkyl derivative thereof,M.sup.2 A.sub.2 (2)whereinM.sup.2 is Cr or Mo andM.sup.3 A.sub.4 (3)whereinM.sup.3 is Ti, Zr or HfAre useful as components of coordination catalysts for olefin polymerization. Lithium compounds of the formula LiA are intermediates used in preparing the above compounds. All of the above compounds are also useful as oxygen-scavenging agents.

Abstract: A poly(dihydrocarbylamide) of a transition metal of groups IV, V or VI is reacted with a hydrocarbyllithium or a silahydrocarbyllithium in a solvent and a hydrocarbyl- or silahydrocarbyl(transition metal) dihydrocarbylamide is recovered. Exemplary is the process of dissolving vanadium tetrakis(dimethylamide) in pentane and adding trimethylsilylmethyllithium to obtain bis (trimethylsilylmethyl)vanadium bis(dimethylamide).
