This has created an exciting opportunity to understand how ethylene signalling may be controlled via metallation
of ETR1 with copper.
Chloro[5,10,15,20-tetrakis-(4-methylphenyl)porphyrinato manganese(III)] (MnTTPCl) was prepared from the corresponding porphyrin base, which was previously reported and fully characterized , by using classical metallation
of the porphyrin-free ligand (in ethanol at porphyrin: manganese ratios of 1: 20-1:30) .

with Ni(II) and Al(III) of 5,10,15,20-tetrakis(phydroxyphenyl)porphyrin: effect of ultrasound," Electrochimica Acta, vol.
of porphyrin and axial ligation with different phenols were further supported by the emergence of two new bands at 500-400 [cm.sup.-1] and 650-350 [cm.sup.-1] assigned to zinc-nitrogen (Zn-NPor)  and zinc-oxygen (Zn-O) vibrational modes, respectively.
Future work will include determination of the quantum yield and metallation
of the compound.
 The metallation
of lithium morpholine to obtain the complex di(morpholine)titanium dichloride is similar to the metallation
of indene and cyclopentadiene to obtain di(indenyl)titanium dichloride and di(cyclopentadienyl)titanium dichloride respectively and they were subsequently developed to enviable demand complexes.
Modifying agents include alkylating, amidating, esterification, metallation
, phosphorylating, sulfonating, oxidizing, and reducing agents.
In order to make sure that metallation
occurs ortho to the boron, the Piers group found it necessary to block the para position with an isopropyl group.

mechanism in TMEDA/metal alkoxide modified anionic polymerization.
Furthermore, in vitro evolution technology has facilitated the discovery of DNAzymes and ribozymes capable of catalyzing a broad range of reactions, including cleavage (1, 21-23) and ligation of nucleic acids (24), porphyrin metallation
(25), and the formation of carbon-carbon (26), ester (27), or amide bonds (28).
[[Eta]] was little affected below about 70% amide group metallation
, but was diminished above 70%, as shown in Fig.
Reactions requiring the use of strong acids such as nitric acid (nitrations) or powerful organometallic bases such as butyl lithium (metallations
) are now routinely possible in flow chemistry.
