a grignard reagent is a source of carbanions and is a useful species in organic synthesis for generating carboncarbon bonds. grignard reagents are named after their founder, victor grignard, a french chemist who earned a nobel prize in 1912 for this discovery. in this tutorial we will explore how to form a grignard reagent the reactivity of a grignard reagent the reaction of grignard reagents with aldehydes and ketones to form alcohols the stereochemistry of a grignard reaction retrosynthesis strategies of a grignard product step 2: a grignard reagent is strongly basic. the grignard reagent acts as a source of r anions, which can act as both a base and a nucleophile. the reaction must be performed in anhydrous conditions, as the presence of water will quench all the grignard reagents. ( rmgbr h2orh homgbr ) what other functional groups will be incompatible with a grignard reagent? select the grignard reagents that contain incompatible functional groups. h2c
