'''Benzylidene compounds''' are, formally speaking, derivatives of benzylidene, although few are prepared from the carbene.   [[Benzylidene acetal]] is a [[protecting group]] in synthetic organic chemistry of the form PhCH(OR)<sub>2</sub>.  For example, 4,6-O-benzylidene-glucopyranose is a glucose derivative.  Benzylidene is an archaic term for compounds of the type PhCHX<sub>2</sub> and PhCH= substituents (Ph = C<sub>6</sub>H<sub>5</sub>).  For example, [[dibenzylideneacetone]] is (PhCH=CH)<sub>2</sub>CO.  [[Benzal chloride]], PhCHCl<sub>2</sub>, is alternatively named benzylidene chloride.

'''Benzylidene''' is the molecule C<sub>6</sub>H<sub>5</sub>CH.  It is a triplet [[carbene]] (CAS RN 3101-08-4).  It is generated by irradiation of phenyldiazomethane.<ref>{{cite journal|title=Comparison of Phenylcarbene and Phenylnitrene
