Isobenzofuran can be prepared from o-phthalaldehyde using hydrosilane. The formed isobenzofuran is trapped by an alkene via a Diels–Alder reaction. Further dehydration proceeds to furnish the conjugated aromatic compound. This multistep reaction was promoted by catalytic amounts of Sc(OTf)3.

Chemical compositions having superior nematicidal properties are formulated. The compositions contain one or more selected aldehydes as the major component and one or more aliphatic or cyclic isothiocyanates as a minor component. Preferred mixtures contain furfural and one or both of methyl isothiocyanate and allyl isothiocyanate. Plant-parasitic nematodes are controlled by contacting the nematodes with the nematicidal compositions, by, for example, applying the compositions to soil or other plant growth media containing the nematodes.
