Alkanes mercury salts

Catalytic forms of copper, mercury and silver acetylides, supported on alumina, carbon or silica and used for polymerisation of alkanes, are relatively stable [3], In contact with acetylene, silver and mercury salts will also give explosive acetylides, the mercury derivatives being complex [4], Many of the metal acetylides react violently with oxidants. Impact sensitivities of the dry copper derivatives of acetylene, buten-3-yne and l,3-hexadien-5-yne were determined as 2.4, 2.4 and 4.0 kg m, respectively. The copper derivative of a polyacetylene mixture generated by low-temperature polymerisation of acetylene detonated under 1.2 kg m impact. Sensitivities were much lower for the moist compounds [5], Explosive copper and silver derivatives give non-explosive complexes with trimethyl-, tributyl- or triphenyl-phosphine [6], Formation of silver acetylide on silver-containing solders needs higher acetylene and ammonia concentrations than for formation of copper acetylide. Acetylides are always formed on brass and copper or on silver-containing solders in an atmosphere of acetylene derived from calcium carbide (and which contains traces of phosphine). Silver acetylide is a more efficient explosion initiator than copper acetylide [7],...

Oxidation of a-amino-acids with silver(ii) picolinate gives almost quantitative yields of nor-aldehydes silver oxide causes further oxidation to the nor-acid. The possibility is suggested of the simultaneous operation of a radical mechanism in solution and a two-electron shift process at the solid silver salt surface. Aryl alkanes and aryl alkanols are oxidized by silver(ii) picolinate to aldehydes and ketones, a-Aminoketones are dehydrogenated by mercury(ii) salts to ketones iminium ions, such as (139), are postulated as intermediates (Scheme 58).
