An electrophotochemical ring-opening bromination of unstrainedtert-cycloalkanols has been developed. This electrophotochemical method enables the oxidative transformation of cycloalkanols with 5- to 7-membered rings into synthetically useful ω-bromoketones without the use of chemical oxidants or transition-metal catalysts. Alkoxy radical species would be key intermediates in the present transformation, which generate through homolysis of the O-Br bond in hypobromite intermediates under visible light irradiation.

An understanding of structure-property relationships in cyanine dyes is critical for their design and application. Anionic and cationic cyanines can be organized into complementary cyanine salts, offering potential building blocks to modulate their intra/

Barbier-type reaction of aryl halides with ketones took place on treatment with samarium diiodide in benzene containing 10% hexamethylphosphoric triamide (HMPA). The reaction involves an aryl samarium as an intermediate.

Solutions of the title compounds R-Ti(OR')3 (1) are generally available from organolithium (or magnesium) derivatives according to equation 1.It is shown (table 1) that some heterosubstituted organotitanium compounds are more stable thermally than their lithium counterparts.The reagents 1 are highly selective carbonylophiles (Tables 1 and 2), their reactivity can be modified by variation of the R'O-group (Table 3) and with the chiral (S)-2-methyl-1-butoxy group an enantioselective addition can be achieved.
