Benzylidene compounds
Encyclopedia
Benzylidene compounds are alkene
derivatives of benzene
.
They are primarily divided into two groups:
Benzylidene is also used to describe a type of protecting group in synthetic organic chemistry of the form PhCH(R)2 For example, 4,6-O-benzylidene-glucopyranose is a glucose molecule whose 4- and 6-OH groups are protected by being bound to a benzylic carbon, forming a benzyl acetal.
