Photophysical properties of dibenzotropylium cation incorporated within acidic ZSM-5 zeolite

Dibenzotropylium ion (DT+) has been generated as an indefinitely persistent species within the channels of ZSM-5 in its H+-form. Diffuse reflectance laser flash photolysis has allowed detection of a transient (two bands: 300 nm, sharp and ~440 nm broad) decaying in the μs time-scale that has been assigned to the corresponding triplet excited state. The tight fit of DT+ within the straight channels (5.2×5.7A?2) of ZSM-5 and the presence of coadsorbed water explain why the DT+ triplet excited state is not quenched by oxygen but interacts with triethylamine, which is highly water-soluble. In the latter case, formation of a new transient compatible with DT· (λmax=270 and 350 nm) through electron transfer from the amine to DT+ triplet is observed.

An efficient, large-scale synthesis of cytenamide

Dibenzosuberenone (5H-dibenzo[a,d]cyclohepten-5-one) was reduced to the corresponding alcohol by sodium borohydride/MeOH and converted to the corresponding 5-chloro compound by thionyl chloride/benzene, treatment of which with CuCN/toluene gave the corresponding nitrile. Hydrolysis by ethanolic KOH yielded the corresponding amide, cytenamide (5H-dibenzo[a,d]cycloheptene-5-carboxamide).

Mapping the active site in a chemzyme: Diversity in the N-substituent in the catalytic asymmetric aziridination of imines

(Chemical Equation Presented) The active site of the aziridination catalyst derived from either the VANOL or VAPOL ligand and B(OPh)3 is larger than expected and can accommodate not only significant substitution on the diarylmethyl unit of the imine but also that alkyl (but not perfluorylalkyl) substituents on the aryl groups lead to enhanced rates and enantioselection. The screen of diarylmethyl N-substituents on the imine revealed that the 3,5-di-tert-butyldianisylmethyl group (BUDAM) gave exceptionally high asymmetric inductions for imines of aryl aldehydes.
