Spirobifluorene: Synthesized spirobifluorene following the reported procedure (page 324-325) using 2-iodobiphenyl as starting material. It was difficult to isolate nmr-clean product and the yield was low, although they reported very high yield. Instead of...
The article presents a synthetic methodology to prepare chiral N,N-disubstituted, 1,2-diamines, which can be convenient precursors to tridentate ligands.
Particularly, I used the synthetic route using cyclohexane-1,2-diamine (both racemic and enatiopure)...
In this manuscript, the single crystalline wires were grown from π-extended porphyrin derivatives TTPH2 1 and TTPZn 2, and their unique electronic properties in OFET devices along with single-crystal structures. 1 was readily obtained in relatively high...
This classic review outlines several therapeutic uses of carbon monoxide (CO). The overall language of the report is very easy to understand and read while presenting in-depth descriptions and examples when needed. This review touches on the primary pathways...
Summary:
This paper reports the synthesis of a Schiff base ligand (L) by reaction of 5,5’-methylene-bis-salicylaldehyde with amidol (2,4-diaminophenol). The applicability of this ligand as a new fluorescent Cu(II) sensor in aqueous medium was assessed. A...
Synthesized mesitylcopper by following the procedure.
(1) High quality anhydrous solvents (THF/dioxane/Toluene) and good argon or nitrogen protection for all the operations are key to get high yield and quality product, since the mesitylcoppor solution is...
1. Synthesized compound 1 and another similar compound using the procedure described in this article.
2. Used 0.2 mmol Iridium instead of 0.1 mmol as reported. The reaction was monitored by TLC and after 48 hrs, all starting materials was consumed. The...
This paper was about first total synthesis of an indole alkaloid, Spirobacillene A and the key step of this approach was a Lewis acid catalyzed spirocyclization of an anisole derivative onto a tethered ynone.
I tried to replicate some of these reactions...
Synthesized (10) on beach in the lab and also pilot plant when I was working in company. The synthesis procedue is reproducible even in a 5 L scale reaction in the lab. The starting material L-Xylose canot be abtained from natural substances which results...
Covalent attachment of small organometallic molecules to COOH-MWCNTs was successfully achieved using the described methods of EDC/NHS coupling. A qualitative yield was achieved which allowed for a unique route to create redox active MWCNTs. After exploration...
Summary:
A new series of bile acid-based trioxanes have been synthesized and assessed for their antimalarial activity against multidrug-resistant Plasmodium yoelii in Swiss mice by oral route.
The Reaction of Interest:
Decarboxylative oxidation of...
The hydrostannation of alkynes is frequently used for the synthesis of vinyl stannanes, which can be subjected to further modifications via a Stille coupling. The major drawbacks of this process result from the difficulties which arise in the control of the...
A pinacle reaction of the synthesis required the cross coupling off a two highly heteroatom functionalised fragments, the use of traditional Heck conditions, such as palladium (II) acetate, triphenyl phosphine and triethylamine afforded poor yields and...
Synthesized 2-[N-( tert -Butoxycarbonyl)amino]thiophene (25) and a similar compound (2-[N-( tert -Butoxycarbonyl)amino]-5-bromothiophene) following the same procedure described in the article as method F.
For the synthesis of 25, the reaction was scaled...
The methodology developed by Montchamp and co-workers demonstrated a mild and reliable way to esterify the monosubstituted phosphinic acids.
I repeated the preparation of substrate 3 as the entry 5 in table 1 followed their protocol. The reaction...
Synthesized similar structures to (13)- "4'-bromo-2',3,5,6'-tetramethoxy-[1,1'-biphenyl]-4-yl trifluoromethanesulfonate" and also other subtitude functional group on 2',3,5,6' position- using the same procedures as are written in the paper in Supporting...
H. Kondo and E. Ochiai Ann. Chem. 1929 470 p224 reported using the iodo group to block Pschorr diazonium cyclizations into an aromatic carbon position when making polycyclic aromatics. This protocol was repeated by K. Goto and H. Sudzuki Bull. Chem. Soc. Jpn...
The manuscript entitled ''A cyclic triphenylamine dimer for organic field-effect transistors with high performance'' is a nice piece of work. A new OFET based on triphenylamine units with a macrocyclic architect has been described with its potential use as...
The preparation of tetramethylguanidium azide was successfully carried out following the literature preparation (JOC 31, 1426 (1966)). Hydrazoic acid was prepared as a Et2O solution by adding conc HCl over 30 minutes to a ice cold solution of NaN3 in...
