While the use of visible light in conjunction with transition metal catalysis offers powerful opportunities to switch between on/-off states of catalytic activity, the next frontier would be the ability to switch the actual function of the catalyst and resulting products. Here we report such an example of multi-dimensional catalysis. Featuring an easily prepared, bench-stable cobalt(I) hydride complex in conjunction with pinacolborane, we can switch the reaction outcome between two widely employed transformations, olefin migration and hydroboration, with visible light as the trigger.

A simple protocol for the selective azidation of alcohols is developed using a solid acid hybrid of a povidone and phosphotungstic acid (PVP-PWA) using azidotrimethylsilane as an azide source at room temperature. In a broad substrate scope, various activated as well as unactivated benzylic and diphenyl alcohols were treated smoothly with TMS-N3 to selectively produce only azide products with excellent yields in a very short reaction time of 2 h. FT-IR confirmed the stability of the catalyst with retention of the Keggins structure after the reaction. Recycling experiments demonstrated the reusability of the PVP-PWA (3?:?1) several times without losing its original activity.

The invention provides a compound of formula (I) or (II) wherein R 1 and R 2 are bound to adjacent carbon atoms and are taken together to form a group -X-SiR' 2 -Y-SiR' 2 -X- or -X-SiR' 2 -X-; each R', which may be the same or different, is a C 1-20 -hydrocarbyl group; each X, which may be the same or different, is O, S, NH; Y is a group X or a bond; each R 3 , which may be the same or different, is a ring substituent or two R 3 groups taken together can form a further optionally R 3 substituted ring (e.g. to form an optionally substituted fluorenyl structure); m is 0 to 5; and n is 0 to 3 and catalysts made using such compounds.

Fraga, Braulio M.,Cabrera, Inmaculada
, p. 530 - 540 (2007/10/03)
The reaction of 5,6-dimethoxy-indanol with acids or with triphenylphosphine-carbon tetrachloride afforded several dimeric compounds; in the dimerisation of 5,6-dimethoxy-indene with SiO2-AgNO3 only a single dimer was obtained.
