Synthetic Route of 1038-95-5, An article , which mentions 1038-95-5, molecular formula is C21H21P. The compound – Tri-p-tolylphosphine played an important role in people’s production and life.
A series of highly reactive metal-free chiral phosphoric acids possessing positively charged phosphonium ion substituents are reported and have been applied to Friedel-Crafts alkylations of indoles and 2,2,2-trifluoromethyl aryl ketones. These catalysts are orders-of-magnitude more active and have similar or better enantioselectivities than their noncharged analogues. High tolerance to a range of substrates with electron-withdrawing and electron-donating substituents was also observed.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 1038-95-5, help many people in the next few years., Synthetic Route of 1038-95-5
