This can be done for example by using a different reagent or changing the temperature or pressure.
The alkyldiisopinocampheylboranes, which result from the addition to alkenes, usefully react with a range of different reagents.
They managed to solve the problem by the use of a variety of different reagents in between baths.
The testing is difficult, since using different anti-D reagents, especially the older polyclonal reagents, may give different results.
There are many different reagents which can be used to label terminal amino acids.
The chemical reactions described as reduction of nitro compounds can be facilitated by many different reagents and reaction conditions.
Aliphatic nitro compounds can be reduced to aliphatic amines using several different reagents:
Turnbull's blue is the same substance but is made from different reagents, and its slightly different color stems from different impurities.
After experimenting with different reagents, he discovered the Jones oxidation.
If you want to test red paint, use a kit with a different reagent, sodium sulfide.
