The reaction mixture was stirred at -78℃ for 30 min and then allowed to warm to ambient tempareture.
The SO group in dimethyl sulfoxide is highly polar. In other words, the dipole moment is very large.
In general, the m-methoxy group is an electron-withdrawing group,while the p-methoxy group is an electron-donating group.
Nucleophilic addiction of Grignard reagents to aldehydes is widely employed for synthesis od alcohols.
It is necessary to maintain strictly anhydrous condition to avoid decomposing the starting material.
The reaction was quenched by pouring 250 mL of saturated aqueous sodium bicarbonate into the reaction mixture.
An ideal gas obeys the following equation: pV=nRT ,where p is the pressure when n moles of a gas occupy a volume V at temperature T.
The single bond in 1,3-butadiene is not equivalent to the corresponding one in n-butane in terms of bond order.
The aromatic rings are neither coplaner nor perpendicular to one another. または、The aromatic rings are not coplanar or perpendicular to one another.
Kinetic resolution is a reaction by which one of the enantiomers is selectively converted into a different compound.
Two phosphines are equivalent in the 31P-NMR spectrum at room temperature due to the facile exchange reaction.
The fact is worth paying particular attention to because of its implications on the validity of the assumption.
