Patterns - Periodic Table
There are certain trends and patterns in the way elements react and behave. For example the format of the periodic table is designed so properties can be easily compared. The atomic nuer of the elements on the periodic table are organized chronologically, starting with Hydrogen with the the atomic nuer of 1, going from left to right.

Fluorinating reagents can react with heterocycles and oxidise rather than fluorinate them. Cross coupling alysts are often poisoned by heterocycles as they stick to the metal permanently. There are some ways to install functional groups on aromatic heterocycles late in a synthesis though, like iridium-alysed borylation.
Interhalogen - Wikipedia
Br 2 reacts with diatomic fluorine in the same way, but at 60 C. I 2 reacts with diatomic fluorine at only 35 °C. ClF and BrF can both be produced by the reaction of a larger interhalogen, such as ClF 3 or BrF 3 and a diatomic molecule of the element lower in the periodic table .
