Matzo them a denser texture than ordinary baked foods made with flour. Hasidic Jews do not cook with matzo, believing that mixing it with water may allow leavening; this stringency is known as "gebrochts". However, Jews who avoid eating "gebrochts" will eat cooked matzo dishes on the eighth day of Passover outside the Land of Israel, as the eighth day is of rabbinic and not Torah origin. Sephardim use matzo soaked in water or stock to make pies or lasagne, known as "mina", "méguena", "mayena" or . Communion wafers used by the Catholic Church as well as in some Protestant traditions
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
