This work reports new kinetic and mechanistic information on the atmospheric chemistry of ketones. Both absolute relative rate methods were used to determine constants for OH reactions with 2-methyl-3-pentanone (2M3P), 3-methyl-2-pentanone (3M2P) 4-methyl-2-pentanone (4M2P), three widely compounds in industry. constitutes first temperature dependence study 2M3P 3M2P. The following values are re...

An inexpensive synthesis of 6-ethynylbipyridine has been accomplished using Sonogashira coupling of 2-bromo-6-iodopyridine with 2-methyl-3-butyn-2-ol. Subsequent Stille coupling with 2-(trimethylstannanyl) pyridine and hydrolysis provided the target compound in an overall high yield.

Asymmetric rotators with a 1,4-bis(ethynyl)bicyclo[2.2.2]octane (BCO) core are needed for engineering crystalline arrays of functional molecular rotors. Their synthesis uses carbinol, 2-methyl-3-butyn-2-ol, as a protecting group because of its polar character and its ability to sustain orthogonal functionalization with the further advantage of being readily removed. The synthesis in good yields...

In the title Schiff base compound, C(15)H(15)N(3)O(2), the azomethine double bond adopts an E configuration. The dihedral angle between the two aromatic rings is 13.4 (12)°. In the crystal, mol-ecules are arranged in wave-like layers parallel to (100) without any classical hydrogen bonding.
