Methyl phenyldiazoacetate is the organic compound with the formula C₆H₅C(N₂)CO₂Me. It is a diazo derivative of methyl phenylacetate. Colloquially referred to as "phenyldiazoacetate", it is generated and used in situ after isolation as a yellow oil.

Methyl phenyldiazoacetate and many related derivatives are precursors to donor-acceptor carbenes, which can be used for cyclopropanation or to insert into C-H bonds of organic substrates. These reactions are catalyzed by dirhodium tetraacetate or related chiral complexes.^[1] Methyl phenyldiazoacetate is prepared by treating methyl phenylacetate with p-acetamidobenzenesulfonyl azide in the presence of base.^[2]^[3]

Solid state structure of t-BuO₂CC(N₂)C₆H₄NO₂, a representative donor-acceptor carbene related to the title compound. Key distances: C-N = 1.329 Å, N-N = 1.121 Å.^[4]
