Children learn through play, and they learn more than adults might expect. Science experiments are a great way to spark their curiosity, get their minds active, and encourage them to do something that doesn¡¯t involve a screen. 10343-06-3, C14H20O10.

Expeditious synthesis of glycosylated phthalocyanines
3,4-Dicyanophenyl O- and S-glycosides in the gluco, galacto, lacto, and cellobiose series were prepared in virtually quantitative yield through nucleophilic aromatic substitution of 4-nitrophthalonitrile with acetyl-protected glycoses and 1-thio-glycoses. Similarly, 2-(3,4-dicyanophenoxy) ethyl 2,3,4,6-tetra-O-acetyl-beta-D-gluco- and galacto-pyranosides were obtained by nucleophilic substitution of 2-(tosyloxy)ethyl 2,3,4,6-tetra-O- acetyl-beta-D-gluco- and -galactopyranoside with 3,4-dicyanophenol in 82% and 94% yields, respectively. All glycosides were deacetylated and tetramerized to the corresponding glycosylated zinc(II) phthalocyanines without further purification using a template condensation in 42-54% yields.
