A porous Zr metal-organic framework, 1-PdBF4 [Zr6O4(OH)4(OAc)2.4{(PNNNP)Pd(MeCN)}2.4(BF4)2.4; PNNNP = 2,6-(HNPAr2)2C5H3N; Ar = p-C6H4CO2-], has been synthesized via postsynthetic oxidative I-/BF4- ligand exchange using NOBF4. 1-PdBF4 enjoys markedly superior catalytic activity and recyclability to its trifluoracetate-exchanged analogue, 1-PdTFA, for the intramolecular cyclization of o-alkynyl anilines and the carbonyl-ene cyclization of citronellal. Moreover, 1-PdBF4 demonstrates a rare example of pore selective catalysis for the cyclization of 2-ethynyl aniline.

A novel palladium-catalyzed approach to 2-benzofuranyl/indolylacetamides from 1-(o-hydroxy/aminophenyl)propargylic alcohols and isocyanides is described. The reaction proceeds through a cascade that includes oxy/aminopalladation, isocyanide insertion, and 1,4-hydroxyl migration. No oxidant or ligand is needed to promote the cascade, and the reactions are carried out under mild conditions to afford the products through high functional tolerance.
The reaction of o-amino aryl carboxylic acids with Grignard reagents. The unusual effect of the N-protecting group on aryl ketone formation
Zhang, Puwen,Terefenko, Eugene A.,Slavin, Joseph
, p. 2097 - 2099 (2007/10/03)
The addition of Grignard reagents to the o-amino aryl carboxylic acids without any additive forms the tertiary carbinol as a major product. Unexpectedly, the aryl ketones are formed as the only isolated product if o-amino moiety of anthranilic acids is protected with Boc, trifluoroacetyl, and pivaloyl protecting groups.
N-Alkylated 2-trifluoromethyl-4-quinolones by addition of base and an alkylating agent to 2-trifluoroacetylaminoacetophenones
Combs,Reed,Klaubert
, p. 323 - 326 (2007/10/02)
2-Trifluoroacetylaminoacetophenones 1 are cyclized to N-alkyl-2-trifluoromethyl-4-quinolones 2 in one pot with concomitant N-alkylation in 40 to 74% yield using potassium hydroxide in acetone containing an alkylating agent.
