The invention provides novel manganese catalysts such as [Mn(
t
BuPc)], which are general for the amination of all types of C(sp
3
)-H bonds (aliphatic, allylic, propargylic, benzylic, ethereal), including strong 1
o
aliphatic C—H bonds, while achieving excellent chemoselectivity, stereospecificity, and high functional group tolerance. We demonstrate the late-stage diversification of bioactive complex molecules that encompass the range of C(sp
3
)-H bond types, such as selective 1
o
C—H aminations of betulinic acid and pleuromutilin derivatives. The catalysts' unprecedented balance of reactivity and selectivity is in part attributed to its mechanism of C—H amination that lies between stepwise and concerted.
Photoactive layers for use in a photovoltaic cell are described. The photoactive layers comprise at least one photoactive ion paired with another ion. This photoactive ion pair can be in the form of an ionic liquid, hydrogen bonded ion pair, cocrystal, or complex to allow for greater flexibility and portability. Also described are photovoltaic cells that contain the described photoactive layers sandwiched between two electrodes.

The present invention relates to a process for the preparation of bis-(2-hydroxyethyl)-disulfide by oxidizing 2-mercaptoethanol with oxygen in a reaction mixture comprising at least one ho- mogeneously distributed iron comprising salt or complex as catalyst and at least one tertiary amine, to bis-(2-hydroxyethyl)-disulfide, obtainable with the process, and to the use of this bis- (2-hydroxyethyl)-disulfide as intermediate in the manufacture of chemical compounds, such as lubricant additives and in the tertiary oil recovery.

The present disclosure relates to a solution comprising a water insoluble carbohydrate and a fluorescent dye, such as a near infrared (NIR) contrast agent, wherein the solution sets under aqueous conditions, such as in vivo, to form e.g. a gel, a glass, a semi-solid, a solid, a crystal or any mixtures thereof. The disclosure further relates to preparation of such solution and use of such solution for in vivo imaging and/or guidance of surgery or interventional therapeutic procedures.
