HS Code: 2931900090
Application
NHC-catalyzed dehydrogenative self-coupling of diphenylsilane: A facile synthesis of octaphenylcyclotetra(siloxane)
A unique application of the CuIPr N-heterocyclic carbene (NHC) to the dehydrogenative self-coupling of diphenylsilane has been discovered. This transformation is carried out open to air at room temperature, yielding octaphenylcyclotetra(siloxane) quantitatively in 1 h. This preparation constitutes a significant improvement over existing methods for the preparation of this compound and demonstrates a novel mode of reactivity for CuIPr. The diphenylsilanone tetramer is the precursor to a number of industrially significant polymers.

Transportation Information
Classification: Non-dangerous goods
HS Code: 2903999090
Status & Application
Status: commercial available
Application:
1) OLED intermediate
2) Organic synthesis
For example:
An efficient protocol for synthesizing dibenzodithiapentalenes
Two new scalable methods for the synthesis of dibenzo[bc,fg]dithiapentalene (2) (DPP) are reported starting from either 1-bromo-3-fluoro-2-iodobenzene over four steps in 57% yield or from THP-protected 3-fluorothiophenol over three steps in 43% yield. Attempts to prepare dibenzodioxapentalene (15) using similar conditions were unsuccessful. Instead, we observed the formation of a macrocyclic dimeric product 16. Fluorine-hydrogen bond interactions were observed by NMR in the F/SH- and F/OH-substituted dibenzothiophene and dibenzofuran intermediates.
