The reaction of organozinc halides RZnX (R=Bu, Ph; X=Cl, Br) with m- and p-bromoacetophenones in the presence of PdCl2(PPh3)2 in THF/HMPA (THF=tetrahydrofuran; HMPA=N,N,N',N',N'',N''-hexamethylphosphoric triamide) takes place chemoselectively to give the corresponding m- and p-R-substituted acetophenones in high yields.Similarly reaction of RZnX with p-bromobenzaldehyde also proceeds chemoselectively to give the p-R-substituted benzaldehyde in good yields.
Regioselective acylation of (5-alkylidene-1,3-cyclohexadiene)tricarbonyliron complexes by the reaction with organometallic reagents

Reaction of [(1,2,3,4-η)-5-alkylidene-1,3-cyclohexadiene]-tricarbonylirons and organometallic reagents generates acyl-[(1,2,3,4,5-η)-1-alkylcydohexadienyl]dicarbonylirons. The acyl group in these complexes migrates to the cyclohexadienyl moiety under carb
Pd-Catalyzed C?H Alkylation of Arenes Using PyrDipSi, a Transformable and Removable Silicon-Tethered Directing Group
Sarkar, Dhruba,Gevorgyan, Vladimir
, p. 11201 - 11204 (2016/08/03)
An efficient Pd-catalyzed ortho-C?H alkylation reaction of arenes using a transformable and removable Si-tethered pyridyldiisopropylsilyl (PyrDipSi) directing group has been developed. In addition, the PyrDipSi directing group allows for an efficient sequential double-fold C?H alkylation/oxygenation of arenes to produce meta-alkylated phenols. This directing group can easily be removed or converted into valuable functionalities, such as aryl, iodo, boronic ester, or phenol.
HOST-GUEST COMPLEXATION-37 SYNTHESIS AND BINDING PROPERTIES OF A TANSACYLASE PARTIAL MIMIC WITH IMIDAZOLE AND BENZYL ALCOHOL IN PLACE.
Cram, Donald. J,Lam, Patrick. Yuk-Sun
, p. 1607 - 1616 (2007/10/02)
The design and 30-step synthesis of a transacylase mimic is described.The target catalyst combines a macrocyclic binding site, a hydroxymethyl goup, and an imidazole group organized to act cooperatively through their attachment to a quaterphenyl support s
