Boroles and borapyramidanes are classical and nonclassical constitutional isomers, resp. It is here shown that they can indeed be interconverted. Treatment of the bis(alkynyl)B(C6F5) SMe2 adduct 3路SMe2 with HB(C6F5)2 gave borole 1路SMe2, featuring trimethylsilyl substituents in both 伪 positions to B, by a 1,1-hydroboration/alkenylboration sequence. Photolysis of the classical borole adduct 1路SMe2 resulted in rearrangement to its nonclassical structural isomer, borapyramidane 2, in high yield, which exhibits a vicinal pair of trimethylsilyl substituents at the square pyramidane base. Neutral borapyramidane 2 is a rare example of an isoster of the (CH)5+ pyramidane cation. Thermolysis of borapyramidane 2 in the presence of SMe2 at 60掳 re-formed borole 1路SMe2, which converted at 100掳 to 2,3-bis-silyl-substituted borole isomer 8路SMe2. Its photolysis also gave borapyramidane 2. Prolonged photolysis of 2 at elevated temperatures converted this to borapyramidane isomer 10 containing a pair of trimethylsilyl groups in 1,3-position at its square C4-pyramidal base. The borole and borapyramidane isomers were characterized by x-ray diffraction, and the system was analyzed by d. functional theory (DFT) calculations In the experiment, the researchers used many compounds, for example, (Chloromethanetriyl)tribenzene (cas: 76-83-5SDS of cas: 76-83-5).
(Chloromethanetriyl)tribenzene (cas: 76-83-5) belongs to organic chlorides. An organic chloride is an organic compound containing at least one covalently bonded atom of chlorine. Their wide structural variety and divergent chemical properties lead to a broad range of names and applications.While alkyl bromides and iodides are more reactive, alkyl chlorides tend to be less expensive and more readily available. Alkyl chlorides readily undergo attack by nucleophiles.SDS of cas: 76-83-5
