Kinetic Form

Hydrogen bromide and hydrogen chloride catalyse the decomposition of methyl trimethylacetate into isobutene, carbon monoxide, and methanol at 370-442� and 450-48O�, respectively. The kinetic form, which is basically 1 : 1, is severely modified by the effect of methanol either produced in the reaction or added initially. Water or alcohols react with an intermediate in the catalysed decomposition of trimethylacetic acid or its methyl ester in esterification-like reactions; some of the resultant esters subsequently decompose to olefin and acid.

Secondary Reactions

Ozone cleavage of 12 substituted vinyl chlorides (1) in methanol occurred such that the chlorinated moiety of the double bond afforded the carbonyl fragment (i.e. acyl chloride) and the nonchlorinated moiety afforded the carbonyl oxide fragment. All of these fragments underwent secondary reactions: formyl chloride gave carbon monoxide and hydrogen chloride; all other acyl chlorides yielded the corresponding methyl esters. The carbonyl oxides were converted into the corresponding methoxy hydroperoxides. Under the influence of hydrochloric acid unsubstituted and monosubstituted methoxy hydroperoxides were dehydrated to form the corresponding methyl esters, whereas the disubstituted methoxy hydroperoxide of acetone produced the cyclic trimeric peroxide of acetone.

Bipyramidal Structure

The products, resulting from addition under mild conditions of the gaseous molecules CO, O2, H2, and HCl, to some rhodium(I)–bis(ditertiaryphosphine) complexes, are described; the [Formula: see text] phosphines used were Ph2P(CH2)nPPh2, n = 1–4, and (+)-diop (diop = 2,3-O-isopropylidene 2,3-dihydroxy-1,4-bis(diphenylphosphino)butane). Monocarbonyls were isolated from addition of CO to [Formula: see text] complexes (n = 1 and 3), the reactions being reversible; there was no reaction with the n = 2 system, while the n = 4 and diop systems absorbed > 1 mol of CO per Rh to give mixtures of products. The same cation precursors add O2 to yield cis-[Formula: see text] adducts (n = 1–3), the binding being reversible for the n = 2 system; pure products were not isolated with the n = 4 cation which absorbs 3 molO2/Rh; the diop system was unreactive toward O2. Reversible additions of 1 mol H2 yield isolable cis-[Formula: see text] complexes with the n = 3 and diop systems; the n = 1 and 2 [Formula: see text] cations are unreactive toward H2, while a mixture of hydrides is formed from the n = 4species. The chlorohydrido cations [Formula: see text] (A = Cl, BF4, PF6, SbF6), n = 1–3, were prepared via routes involving addition of gaseous HCl to precursor [Formula: see text] complexes; however, the reactions with the n = 4 and diop systems did not yield pure products.The solution structures of all the isolated five- and six-coordinate addition products have been determined using 1H and variable temperature 31P nmr. The five-coordinate carbonyl with n = 1 shows equivalent phosphines from −50 to 25 °C, while the n = 3 system shows inequivalent phosphines resulting from a trigonal bipyramidal structure with an equatorial carbonyl. The [Formula: see text] cation, n = 3, has cis geometry, while trans-structures are preferred for the n = 1 and 2 species.

Gaseous Products

A study was made on the decomposition of PCB's in a radio-frequency glow discharge plasma. PCB's were completely decomposed in plasmas of a few Torr of oxygen, hydrogen, and water vapor. Gaseous products from PCB's in an oxygen plasma were carbon monoxide, carbon dioxide, water, hydrogen chloride, chlorine, and chlorine dioxide. Hazardous compounds such as phosgene and vinyl chloride were not detected by gc–ms analysis. The total quantity of oxygen flowed past the sample was only about three times the stoichiometric oxygen required for the perfect oxidation of PCB's. In a hydrogen plasma, PCB's gave ethane and isobutane as major gaseous products and several higher hydrocarbons as minor products. Almost all of the chlorine in PCB's was converted to hydrogen chloride. Major products from PCB's in a water vapor plasma were carbon dioxide, carbon monoxide, and hydrogen chloride. No other products were detected. The mechanisms for reactions occurring in plasmas are discussed. The importance of the wall effect for the formation of solid products is discussed.
