cf. CA 56, 3508h. Reactions of (RO)₃P and R’OH(R = Et, Bu, and allyl, and R’ = Et, Bu, tert-Bu, and allyl) with CCl₄ or BrCCl₃ to yield (RO)₃PO and phosphorylation products of the alcs. are summarized. By suitable choice of phosphite and alc., the reaction provides a useful method of oxidation of phosphites or phosphorylation of alcs. The reaction proceeds by a radical-chain process involving solvolysis of an intermediate quasiphosphonium derivative, [(RO)₃PCCl₃]⁺Cl^–.

Burn, A. J. published the artcileThe reactivity of organophosphorus compounds. XVII. A novel oxidation of some tervalent compounds: reduction of carbon tetrachloride to chloroform by trialkyl phosphites, Category: chlorides-buliding-blocks, the publication is Journal of the Chemical Society (1963), 5788-96, database is CAplus.

cf. CA 58, 13780a. (RO)₃P react with R’OH in the presence of CCl₄ or BrCCl₃ to give the corresponding trialkyl phosphate, CHCl₃, and an alkyl halide (when R = R’). Small quantities of the dialkyl trichloromethylphosphonate are also formed under some conditions. Variation of the phosphite and alc. (R ≠ R’) leads to mixtures of phosphates, but when R’ = tert-Bu, oxidation to (RO)₃PO occurs. The results are discussed in terms of solvolysis of intermediate quasiphosphonium ions of the type [(RO)₃PCCl₃]⁺. Similar reactions involving Ph₃P and (PhO)₃P with EtOH and polyhalomethanes have been investigated.

B₂H₆ (I) reacted with MeONH₂ (II) in Et₂O at -112° to form MeONH₂BH₃ (III), m. 55°. Hydrolysis of III with dilute HCl gave 93% of the original II, and all 3 of the hydridic H was recovered; hydrolysis with 50% KOH at 100° gave reduction of II to NH₃ and only 2/3 of the hydridic H was recovered. No reduction was observed when pure II was heated with 50% KOH. I reacted with MeONHMe (IV), with or without Et₂O, to give MeONHMeBH₃ (V), m. -23 to -21°. I reacted with NMe₃ at 0° to give an 86% yield Me₃NBH₃ (VI). Acid hydrolysis of V gave H₃BO₃ and the salt of IV; basic hydrolysis gave 27% MeNH₂ and other amines. Pure IV was unaffected by 50% KOH at 100°. Only 2/3 of the hydridic H of V was obtained by hydrolysis. I and MeONMe₂ (VII) gave MeONMe₂BH₃ (VIII), m. -16.5 to -16.0°, vapor pressure 3.8 mm. at 25°. VIII and NMe₃ reacted to regenerate 98% of the original VII. Basic hydrolysis of VIII gave 92% of the original VII and 90% of the hydridic H. III, V, VIII lost H on standing; 50% decomposition in 24 hrs. required temperatures of 55, 65, and 90°, resp. Reaction of III with BF₃ in Et₂O at 0° did not produce I and H evolution increased. Reaction of III with NMe₃ gave 22% VI; H loss was again increased. NH₃ had a similar effect. The pyrolysis of III, V, and VIII is discussed, and mechanisms for H loss and amine reduction during basis hydrolysis are suggested. When I reacted with II containing NH₃ in Et₂O, the etherate of H₂NB₂H₅ (IX) was obtained. Pure IX was obtained by complexing the Et₂O with AlCl₃ or BF₃.
