Synthesis of Benzonitrile 4
Synthesis of Benzonitrile 4
A variety of functional groups (e.g., alkoxy, phenyl, methylthio, benzyloxy, trifluoromethyl, or chloro) were compatible with the conditions used. Arylsilanes bearing substituents at the para-, meta-, and ortho-positions were all converted to the corresponding benzonitriles (2b, 2h, and 2i, respectively) in good yields.

Benzyl alcohol
CAS number: 100-51-6
Benzyl alcohol is a colorless liquid with a mild, pleasant, aromatic odor.
Benzyl alcohol 1a was reacted with 1.25 equivalents of phenylphosphonyl dichloride (PPDC; PhP(O)Cl2) in the presence of triethylamine (Et3N) to afford a mixture of mono- and bis-phosphates. The monosubstituted product was reacted directly with p-cresol without purification to afford the desired phenylphosphonate 2a.

Porphyrin
CAS number: 101-60-0
Porphyrin is a group of organic heterocyclic compounds that are comprised of four modified pyrrole subunits connected via methine bridges and form an aromatic macrocyclic structure, which has one or more side chains attached. Many porphyrins are naturally occurring pigments. Porphyrins with metal ions bound to the porphin ring can be cofactors for biological processes, such as oxygen transport by hemes and photosynthesis by chlorophyll.
