  The present invention is related to a hydrocarbon oxidation process. The process comprises bringing one or more hydrocarbons into contact with a source of oxygen in the presence of a radical initiator and a catalyst. The catalyst comprises an organic metal complex located on a catalyst support, and is obtained by partial decomposition of the organic metal complex. For example, the process can be used to produce dimethyl carbonate from dimethoxy methane. The invention is also related to a partially decomposed catalyst that comprises a silica support and an organic metal complex, wherein at least 5% of the organic compound remains in the catalyst. The organic metal complex comprises an organic compound and a metal-based compound wherein the metal is selected from copper, nickel, and combinations thereof. The invention is also related to a process for manufacturing of a catalyst comprising mixing L-arginine, a Cu-based compound, water, and optionally another metal-based compound to form a solution; impregnating the solution onto a silica support to form a catalyst precursor; and partially decomposing the L-arginine to form the catalyst so that at least 5% of L-arginine remains in the catalyst.

  catalytic oxidation reactions, were readily oxidized by hydrogen peroxide or monopersulfate, under acidic or neutral conditions in water, to form novel metal complexes derived from the facile oxidation of the PcS ring. Meso-nitrogen-oxide derivatives and metal-biliverdin-like derivatives were identified among the products at early reaction times, whereas at longer times fragmentation of the phthalocyanine

• Visible photostability of some ruthenium and platinum phthalocyanines in water and in the presence of organic substrates

  Water-soluble, metal-tetrasubstituted phthalocyanines ( -SO₃H , MPcS and -COOH , MPcC) of platinum and ruthenium were synthesized and their photostability to visible light irradiation was determined. For the ruthenium phthalocyanines, the characteristic visible Q band of the phthalocyanines was almost totally suppressed after five days of irradiation. The platinum derivatives were instead more resistant to photodegradation, and the Q band did not decrease by more than 25%. The addition of carbonyl compounds to the phthalocyanine solution in water (at concentrations at least 1400-fold those of the phthalocyanines) dramatically accelerated the photobleaching of these phthalocyanine complexes. PtPcS turned from blue to green and to colorless with one day of visible-light irradiation in the presence of acetone. This effect decreased with the increase in molecular weight of the ketones (from acetone to 2-pentanone). The addition of alcohols (i.e. 1-butanol) or other organics (i.e. phenylacetic acid) did not affect the photostability of these metal-tetrasubstituted phthalocyanines. Dioxygen also had an important role, as when the solutions of phthalocyanines were carefully deaerated before irradiation, the visible spectra were preserved. The platinum phthalocyanines, as with the palladium analogs, sensitize the photoproduction of ¹O₂ , as shown by the formation of endoperoxide and its rearranged products in the presence of furfuryl alcohol (a singlet oxygen trapping agent).

  合成了铂和钌的水溶性金属四取代酞菁（-SO3H , MPcS 和 -COOH , MPcC），并测定了它们在可见光照射下的光稳定性。对于钌酞菁，酞菁特有的可见光 Q 波段在照射五天后几乎完全被抑制。而铂衍生物对光降解的抵抗力更强，Q 带的下降幅度不超过 25%。在酞菁水溶液中加入羰基化合物（浓度至少是酞菁的 1400 倍）会显著加速这些酞菁复合物的光漂白。在有丙酮存在的情况下，PtPcS 在可见光照射一天后就会由蓝变绿，最后变成无色。这种效果随着酮类（从丙酮到 2-戊酮）分子量的增加而减弱。加入醇类（如 1-丁醇）或其他有机物（如苯乙酸）不会影响这些金属-四代酞菁的光稳定性。二氧也起着重要作用，因为当酞菁溶液在辐照前经过仔细的脱氧处理后，其可见光谱得以保留。铂酞菁和钯酞菁类似物一样，能敏化 1O2 的光生成，在糠醇（一种单线态氧捕获剂）存在下形成的内过氧化物及其重排产物就证明了这一点。
