(2-METHYLBUTA-1,3-DIENE). Isoprene is a low boiling liquid (boiling point 35°C
) which polymerizes even at room temperature. Natural rubber is an important
source which gives isoprene on distillation. Other methods used for the synthesis

[9] Treatment of 2-methylbuta-1,3-diene with dry gaseous hydrogen bromide at –
208C produces the corresponding 1,2-adduct, which rearranges upon standing
to give its isomer.[10] The latter conditions can also be applied to prepare ...

Thus, it is30times more reactive than 9-vinyl-9-borabicyclo[3.3.1]nonane in a
reaction with 2-methylbuta-1,3- diene. [67] Bromoboranes are even more reactive
and ...

Most naturally occurring polymers are condensation polymers, but natural rubber
can be regarded as an addition polymer. The monomer is 2-methylbuta-1,3-
diene (isoprene), whose formula is shown in figure 27.5. When dienes of this sort

N-Heterocyclic Carbenes in Synthesis
Isoprene (2-methylbuta-1,3-diene) is another attractive substrate that provides a
potential route into terpenoid compounds [5, 6]. However, non-symmetrical 1,3-
dienes increase the number of possible telomer products due to the additional ...
monomers are buta-1,3-diene; 2-methylbuta-1,3-diene (better known as isoprene
); 2,3-dimethybuta-1,3-diene and 2-chlorobuta-1,3-diene (better known as
chloroprene). Polymerisation of these materials via the 1,4 position yields
polymers ...
