Acetylene incompatibilities with

Several other fuels were examined by Gilliland in zero OB mixts with TeNMe, but it was found that some fuels are incompatible with TeNMe. Most notably, acetylene is only very si sol in it and metallic salts, such as Mercuric Cyanide and Mercuric Fulminate, are insoluble...

Thus, this atom is activated on specific sites on the MgO surface. From FTIR studies, it is known that Pd atoms already diffuse upon deposition to F centers and it is this defect site, which activates Pd by a substantial charge transfer [490]. This increases the possibility for binding and activating the third acetylene molecule. Theory predicts Pd atoms to be also activated at MgO(Oic) low-coordinated sites [490], but the energetics of the reaction on these sites is totally incompatible with the desorption peak of the product molecule at 215 and 300 K (Fig. 1.100). This further supports the presence of a single active center, namely Pd/MgO(F). 

Photolysis at 365 nm in CH3CN improves the rate of DDQ promoted cleavage of benzyl ethers in that under these conditions cleavage occurs at rt. The MPM groups is still cleaved more rapidly and good selectivity can be achieved over benzyl ether cleavage. Unfortunately, olefins and acetylenes are incompatible with this protocol." ...
