conjugated diene and a
substituted alkene,
commonly termed the
dienophile, to form a

- (or DA) reaction, the
DAINV is a
cycloaddition between an electron-rich
dienophile and an electron-poor diene.
During a
DAINV reaction,

- reaction, a [4+2] cycloelimination. It
involves the
formation of a
diene and
dienophile from a cyclohexene. It can be
accomplished spontaneously with heat, or...

reaction between 1,3-butadiene and
dienophiles of low
reactivity usually requires prolonged heating above 100 °C. Such...
