A novel sodium N-fatty acyl amino acid (SFAAA) surfactant was synthesized using pupa oil and pupa protein hydrolysates (PPH) from a waste product of the silk industry. The aliphatic acids from pupa oil were modified into N-fatty acyl chlorides by thionyl chloride (SOCl2). SFAAA was ...
Moreover, the method enables use of the more gentle Mukaiyama reagents rather than acid chlorides for acylation. On the basis of these observations we propose the following mechanism. The 1-acyldipyrromethane-BR2 complex (6-BR2) in principle requires only 1 equiv of EtMgBr owing to the ...
(1973) show that even with amine promoters, acylation of silylketene acetals (SKA) does not occur with acyl chlorides when the SKA contains two α-substituents. Polymerizing methacrylate chain ends have two such substituents. These references further disclose that a stoichiometric amount of amine ...

The effect of the electronic nature of the para substituent on the aromatic ring of 2-aryloxypropionyl chlorides on the stereochemical outcome of the acylation of 3,4-dihydro-3- methyl-2H-[1,4]benzoxazine and its 7,8-difluoro-containing analogue has been studied. The geometries of the ...
In contrast to typical acyl electrophiles such as acid chlorides, acid fluorides are uncommon acyl electrophiles to use in boron‐based coupling probably due to a high level of stability toward nucleophiles. This first attempt to use acid fluorides as a coupling partner with boronic acid allowed ...
