چکیده
SN2 rection between 4-(tert-butyldimethylsilyl)hex-5-yn-1-yl 4-methylbenzenesulfonate and NaN3 in DMF at 80 °C provided (6-azidohex-1-yn-3-yl)(tert-butyl)dimethylsilane intermediate, which underwent situ intramolecular thermal Huisgen azide–alkyne cycloaddition reaction. This one-pot process gave 4-(tert-butyldimethylsilyl)-4,5,6,7-tetrahydro-[1,2,3]triazolo[1,5-a]pyridine 78% yield.

RNA synthesis using 2'-O-(tert-butyldimethylsilyl) protection.
This chapter enables the reader to carry out the solid-phase synthesis of ribonucleic acid (RNA) using beta-cyanoethyl phosphoramidite chemistry combined with tert-butyldimethylsilyl protection of the ribose 2'-hydroxyl group. Phosphoramidite monomers are activated with 5-benzylmercapto-1H-tetrazole enabling fast and highly efficient coupling to the 5'-hydroxyl group of the support-bound oligon...
متن کاملFacile synthesis of uniform large-sized InP nanocrystal quantum dots using tris(tert-butyldimethylsilyl)phosphine
Colloidal III-V semiconductor nanocrystal quantum dots [NQDs] have attracted interest because they have reduced toxicity compared with II-VI compounds. However, the study and application of III-V semiconductor nanocrystals are limited by difficulties in their synthesis. In particular, it is difficult to control nucleation because the molecular bonds in III-V semiconductors are highly covalent. ...

متن کاملMass spectra of tert-butyldimethylsilyl ether derivatives of the major metabolite of prostaglandin F.
The EI mass spectra of four tert-butyldimethylsilyl ether derivatives of the major metabolite of prostaglandins F1 alpha and F2 alpha (PGF-M) are presented and discussed. Proposed ion assignments and fragmentation pathways are based on substituent shifts, on data from a deuterium-labeled methoxime analog, and on the analysis of collision-induced dissociation spectra of selected ions. Fragment i...
متن کامل4-tert-Butylpyridinium triiodide–4-tert-butylpyridine (1/1)
The title compound, C(9)H(14)N(+)·I(3) (-)·C(9)H(13)N, consists of monoprotonated 4-tert-butyl-pyridinium cations and triiodide anions. The triiodide ion has near-symmetric linear geometry, with bond lengths of 2.9105 (4) Å (I-I) and a bond angle of 177.55 (3)° (I-I-I). For this room-temperature structure, the butyl group on the pyridine ring is disordered and has been treated as a rigid rotato...
