Yanagisawa S, Ueda K, Sekizawa H, Itami K: Programmed synthesis of tetraarylthiophenes through sequential C-H arylation. J Am Chem Soc. 2009 Oct 21;131(41):14622-3.
The utilization of three catalysts, RhCl (CO){P [OCH (CF (3))(2)](3)}(2), PdCl (2)/P [OCH (CF (3))(2)](3), and PdCl (2)/bipy, enables regioselective sequential arylations at the three C-H bonds of 3-methoxythiophene with iodoarenes. |

Kingsley S, Chandrasekhar V, Incarvito CD, Lam MK, Rheingold AL: Tethered pyrazolyl phosphinate: pyrazolyl-N- and phosphoryl-O-metal coordination in Ph (2) P (O)[OCH (2) CH (2)(3,5-Me (2) Pz)]. Inorg Chem. 2001 Nov 5;40(23):5890-6.
In this paper, we report a new tethered pyrazolyl phosphinate, Ph (2) P (O)[OCH (2) CH (2)(3,5-Me (2) Pz)] DPEP (1), where the pyrazolyl group is separated from the phosphorus by means of an ethyleneoxy spacer. 1 has two potential coordination sites in the form of a phosphoryl oxygen atom and a pyrazolyl nitrogen atom. 1 forms hydrolytically stable complexes, (DPEP-CoCl (2))(n)(2), (DPEP)(2)-CuCl (2) (3), (DPEP-ZnCl (2))(n )(4), and (DPEP)(2)-PdCl (2) (5). |
