This invention is a new and distinct grapevine variety denominated ‘IFG Forty-one’. The new grapevine is characterized by producing small naturally seedless red berries having a broad ellipsoid shape with a unique combination of muscat and labrusca flavor. The strong fruity flavor is reminiscent of strawberries. Fruits normally ripen mid-season.
The process of the invention involves reacting a phenol with a dialkyl disulfide in the presence of a zirconium phenoxide catalyst to prepare the corresponding ortho-(alkylthio)phenol.
