Trimethylsilyl ethers are too susceptible to solvolysis for them to have any utility as protecting groups.

The tert-butyldimethylsilyloxy group is ca. 10 4 times more hydrolytically stable and holds more promise for such applications. When the commercially available tert-butyldimethylsilyl chloride TBDMS-Cl was initially used as a silylation agent it was found by E.

Molecular Representations Converting between Bond-line Lewis and Condensed structures One of the foundations and a key transition from General to Organic Chemistry is the deep insight of molecular structures and learning the concept of Bond-Lile Zig-Zag representation. Here is the much-needed to-the-point summary linking the Bond-line Lewis and Condensed structures. Catalytic cycle of.

L 2 Pd 0 Cl-can be generated from Pd 0 L 2 in the presence of a chloride ion. 24 Therefore it is possible that an anionic palladium complex is the real catalyst in the catalytic cycle. As discussed previously amide is typically the base used in the Sonogashira reaction and it is proposed that a π-alkyne-copper complex is formed to increase the acidity.
