“…To study the reactivity of the resulting phenol 3 , we performed a nucleophilic substitution reaction on a model molecule, 4 ,19 containing the same functional groups as in the phosphorus dendrimers we wished to use. Under basic media in THF, at 50 °C, the first organocatalyst, 5 , prepared in this work was obtained in 94 % yield (Scheme ) 20.…”

The hydrodeoxygenation (HDO) of maize oil was performed in an autoclave with Mo‐based catalysts supported by different carbon materials, such as reduced graphene oxide, activated charcoal, graphite, and fullerene. Nanostructured Mo‐based catalysts with different phase compositions were prepared by using the carbothermal hydrogen reduction method at temperatures ranging from 500 to 700 °C and characterized by Raman spectroscopy, N2 adsorption isotherms, SEM, TEM, XRD, X‐ray photoelectron spectroscopy, and ammonia temperature‐programmed desorption. The highest total hydrocarbon yield of 90.32 % was obtained on the reduced graphene oxide‐supported molybdenum carbide catalyst at 700 °C. These results are subject to the complicated effect of different factors such as phase composition, defect concentration, and particle size on the catalytic behavior of the materials. Unique structures of different supports also play a significant role in the HDO reaction. On the basis of the results of comprehensive analysis of products and catalysts, an HDO mechanism was proposed. These Mo‐based catalysts are a promising system to prepare high‐quality diesel fuels from renewable resources.

“…These reactions led for instance to multitri-or multitetra-functionalized dendrimers, meaning dendrimers having simultaneously three [40] or four [11] types of functional groups on the surface, such as compounds 18-G n and 19-G n (Scheme 8). Tetraazamacrocycles were also grafted to dendrimers in this way [41]. A particular illustration of the reactivity of P(S)Cl 2 end groups with amines is given by the reaction of dendrimers 1-G n Phosphorus-Containing Dendrimers: From Material Science to Biology 479 FIGURE 2 Structure of the third generation dendrimer complex 14-G 3 .…”
