1,4 Dimethoxybenzene

The cyclic carbonate is easily cleaved by refluxing in water for 30 min. It can be converted to the 1,2-dimethoxybenzene derivative (aq. NaOH, Me2S04, reflux, 3 h). ... 

Dendrimer 1 + is a classical example of a dendrimer containing a luminescent metal complex core. In this dendrimer the 2,2 -bipyridine (bpy) ligands of the [Ru(bpy)3] +-type core carry branches containing 1,2-dimethoxybenzene- and 2-naphthyl-type chromophoric units [15].

Urticants are relatively unstable and tend to decompose spontaneously unless stored at low temperatures. Below —4°F, they can be kept for extended periods. Solvents including 1, 2-dimethoxybenzene, ether, dioxane, nitromethane, and glycine act as stabilizers and may be added to help prevent decomposition of agents during storage. Agents can be stored in glass or enamel-lined containers. Urticants rapidly attack rubber and metals, especially iron. 

The photochemical deprotection of sulphonamides to free amines is synthetically useful193. This process is caused by electron transfer from an electron-donating sensitizer such as 1,2-dimethoxybenzene or 1,4-dimethoxybenzene and the presence of reductants like ammonia or hydrazine is also required194 (equation 139). 

All the 3-diazoindazoles 2, irradiated in an aromatic solvent (benzene, p-chlorotoluene, benzonitrile, 1,2-dimethoxybenzene), gave by ring substitution the corresponding 3-arylindazoles in variable yields (66LA17). 3-Diazoindazole 2b, irradiated in pyridine and in thiophene, gave the 6-chloro-3-(2-pyridyl)-indazole and the 6-chloro-3-(2- or 3-thiophenyl)-indazole (66LA17). 

Detailed NMR and theoretical studies have identified and characterized a number of the complexes along the proposed reaction pathways for anisole, 1,2-dimethoxybenzene and Al,Al-dimethylaniline ° . For example, anisole deaggregates the BuLi hexamer to form a tetrameric BuLi-anisole complex 4. Adding TMEDA displaces the anisole from the tetramer and breaks it down further to give a BuLi-TMEDA dimer 5, which deprotonates anisole at >0°C yielding 6 (Scheme 4).

Efficient synthesis of 6,7-dimethoxybenzopentathiepin 102 and 6-(2-aminoethyl)benzopentathiepin 103 (Figure 29), which are sectional structures of varacin, were proposed from 1,2-dimethoxybenzene and 1,2-benzene-dithiol, respectively <1995H(41)893>.
