26 - 178A New Way to Prepare Grignard Reagent from RX (X: Cl, Br)Using the Mixture of BrCH2CH2Br and I2 as an Initiator. —Using 1,2-dibromoethane and iodine as initiators in the preparation of Grignardreagents reduces the reaction times by a factor of about 2-3. Compared toconventional methods a higher purity of the Grignard compounds is achievedor conventional methods do not yield the Grignard compound at all (no yieldsgiven). — (LI, JING; LIAO, XIANGJUN; LIU, HUA; XIE, QINGLAN; LIU,ZHUN; HE, HILIN; Synth.
