This paper reports the preparation, properties, and structure of new SF5Br-fluoroolefin adducts. The extent and direction of SF5Br addition to fluoroolefins have been studied with seven fluoroolefins. Steric factors appear to be important for this addition.

Photochemical reactions of trichlorosilane, methyldichlorosilane, or trimethylsilane with vinyl fluoride gave the corresponding 2-fluororoethylsilanes (90–95% yields), hydrolysis or pyrolysis of which occurred viaβ-elimination of fluorine. The photochemical reaction of trichlorosilane with 1-chloro-2-fluoroethylene gave both 1:1 adducts. These were reduced by further reaction with silanes (SiHCl3,

The reaction of phosphorus trichloride and oxygen with fluoro-olefins gives mixtures containing phosphoric and phosphonic dichlorides together with C–C cleavage products. In a wide range of compounds of the type (RO)2P-(O)·CHX·CHYCl, including productsderivedfrom these reactions, elimination of HCl occurs stereospecifically or stereoselectively, and in the case of pairs of diastereoisomers stereoconvergently
三氯化磷和氧气与氟代烯烃的反应生成的混合物含有磷酸二氢膦和膦二膦以及CC裂解产物。在各种各样的(RO)2 P-(O)·CHX·CHYCl类型的化合物中,包括从这些反应中衍生的产物,HCl的立体定向或立体选择性消除,在成对的非对映异构体对中会聚。带有X和Y顺式的烯烃(RO)2 P(O)-CX CHY 。有人建议通过1 H和19 F nmr研究确定的基态构象性质与观察到的HCl消除方式之间的相关性。

A novel 1,2-FCl interchange mechanism is proposed to be involved in the unexpected thermal conversion of CH2ClCHF2 to 1,2-difluoroethylene.
