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. 301224-40-8, C31H38Cl2N2ORu. A document type is Patent, introducing its new discovery., Safety of (1,3-Dimesitylimidazolidin-2-ylidene)(2-isopropoxybenzylidene)ruthenium(VI) chloride
The present invention refers to novel ruthenium- and osmium-based catalysts for olefin metathesis reactions with high Z-selectivity. The effect is obtained by utilising two monoanionic ligands (X) and (L1) of very different steric requirement. The catalysts selectively provide the Z-isomer even in presence of air or of acids. Claimed are formulae (A) and (B); The anionic ligand “X” is defined as -CN, -N3, -NCO, -CNO, -NCS, and -NCSe. Specific embodiments for these catalysts are:
