Substitution and Orientation in the Benzene Ring.

“…with no decomposition. The complexes of ethers with boron chloride, however, decompose on warming to give alkyl chlorides and esters of boric acid (49).…”

Reactions Of Boron Trichloride With Organic Compounds

“…The methanoland ethanol-boron trichloride systems have been investigated using a high-vacuum line technique; the reactions were carried out at -60°to -80°C., owing to their exothermal nature, and were immediate and quantitative (163). Three further reactions (equations 7, 8, and 15) were recognized in the methanol system (133,162,163). The products of equations 7 and 8 are dialkyl chloroboronates and alkyl dichloroboronites, respectively; these as well as trialkyl borates may be used for synthesizing other organic boron compounds (102).…”

“…The reaction between ethers (R in R20 = CH3, C2H6, R-C3H7, n-CsHu) and boron trichloride was originally thought to produce hydrogen chloride (45), but later it was recognized that diethyl ether forms a 1:1 complex (56). A detailed study of the diethyl etherand dimethyl ether-boron trichloride systems was made, using a high-vacuum technique; the initial reaction was extremely rapid and exothermal, and the complete sequence is represented by scheme 30 (133,164).…”

Coördination Compounds of Boron Trichloride. I. A Review.

“…More recently, Wiberg and coworkers (51,67) have proposed that boron oxychloride, BOC1, is one of the products obtained when BC120C2H6 is heated to 50°C. They did not isolate this compound nor has its existence been proved.…”

“…He stated that boron trichloride is soluble in ether and forms a crystalline, difficultly fusible, double compound with it. According to Wiberg and coworkers (51,68,69,70) boron trichloride reacts with ethers to form mono-and di-alkyl substitution products. With an excess of methyl ether at -80°C.…”
