Visible light-mediated metal-free double bond deuteration of substituted phenylalkenes

Various bromophenylalkenes were reductively photodebrominated by using 1,3-dimethyl-2-phenyl-1H-benzo-[d]imidazoline (DMBI) and 9,10-dicyanoanthracene. With deuterated DMBI analogs (the most effective was DMBI-d11), satisfactory to excellent isotopic yields were obtained. DMBI-d11 could also be regenerated from the reaction mixtures with a recovery rate of up to 50%. The combination of the photodebromination reaction with conventional methods for bromoalkene synthesis enables sequential monodeuteration of a double bond without the necessity of a metal catalyst.

Visible light photoredox catalyzed cascade cyclizations of α-bromochalcones or α-bromocinnamates with heteroarenes

Vinyl radicals were generated from α-bromochalcones or a-bromocinnamate ethyl ester under visible light photoredox catalyzed conditions via an oxidative quenching cycle of the iridium complex [Ir{d(CF 3)ppy}2(dtbbpy)]PF6 and subjected to cascade cyclizations with heteroarenes entailing two consecutive C-C bond formations and three C-H activations. The process is amenable to furans, benzofurans, pyrroles, and indoles, giving rise to a broad variety of novel polycyclic frameworks in high yields under mild and environmentally benign reaction conditions.

A novel and one step procedure for preparation of α-bromo-α,β-unsaturated carbonyl compounds

A new one step method is developed for the preparation of α-bromo-α,β-unsaturated carbonyl compounds in moderate to good yields from corresponding α,β-unsaturated carbonyl compounds using DMP [1,1,1-triacetoxy-1,1-dihydro-1,2-benziodoxol-3(IH)-one] and te

Synthesis of allenes from allylic alcohol derivatives bearing a bromine atom using a palladium(0)/diethylzinc system

A general and efficient synthesis of allenes using a palladium(0)/diethylzinc system is described. Treatment of mesylates or trichloroacetates of (E)- or (Z)-2-bromoalk-2-en-1-ols with diethylzinc in the presence of a catalytic amount of palladium(0) affords allenes bearing an aminoalkyl, alkyl, or aryl substituent(s) in good to high yields. No transfer of chirality from the stereogenic center carrying the mesyloxy group to the allene was observed.

A convenient and useful method of preparation of α-bromo enones from the corresponding enones using organic ammonium tribromide (OATB)

Various acyclic α-bromo enones 2 as well as cyclic α-bromo enones 4 can be prepared from the corresponding acyclic enones 1 and cyclic enones 3 respectively, in a one-pot procedure by employing organic ammonium tribromide, such as cetyltrimethylammonium t
