Abstract: Abstract In the following study, we investigated thermally and photolytically induced transformations of acylcyclotetrasilanes (Me3Si)2Si4Me8(Me3Si)COR (compounds 9a-c; R = alkyl, aryl). Mild thermolysis of 9a-c below 130 °C cleanly and selectively afforded the corresponding endocyclic silenes 10b-d irrespective… read more here.

Abstract: A novel mechanism of organobase-mediated Brook rearrangement and C-C coupling in the copper-catalyzed reductive coupling of benzaldehyde and benzophenone is proposed. The results demonstrate that this reaction proceeds mainly through five sequential elementary steps: transmetalation,… read more here.

DOI: 10.1039/c9ra05482k
Abstract: Asymmetric retro-[1,4]-Brook rearrangement of 3-silyl allyloxysilanes has been developed involving Si-to-C chirality transfer, which is diastereoselective without loss of enantiomeric excess. read more here.
