Matzo (steamed) immediately after rice flour is mixed with water and they pierce it many times with handle of the spoon to let out steam so that the bread will not rise (this custom is called "juthante kannu kuthal" in the Malayalam language meaning "piercing the bread according to the custom of Jews"). This bread is cut by the head of the family and shared among the family members. In Israel, the Saint James Vicariate For Hebrew Speaking Catholics uses matzo as the host for the Eucharistic celebration in the Mass as a form of inculturation. At the end of World
Meta-selective C–H functionalization copper catalyzed C–H arylation. "Meta"-olefinated biologically important biphenyl, amino acid and Baclofen derivatives have been accessed by remote C–H activation assisted by the "end-on" template. These demonstrate the potential applications of meta-selective C–H functionalization in medicinal chemistry. Meta-selective C–H functionalization "Meta"-selective C–H functionalization refers to the regioselective reaction of a substituted aromatic ring on the C–H bond "meta" to the substituent. Substituted aromatic ring is an important type of substructure in pharmaceuticals and industrial compounds. Thus, synthetic methods towards substituted aromatic rings are always of great interest to chemists. Traditionally, regioselectivity on the aromatic ring is achieved by the electronic
