A related ligand, MPL (3-methoxypropanol), was combined with Al(f-Bu)3 and Al(Me)3 [28]. The resulting Bll compound was similar to those formed by MEL, with a dative interaction in the methyl compound but not the f-butyl one. However, the dative bond is much longer (2.39 A vs. 2.27 A) for the propyl compound. Another related ligand is MlP(l-methoxy-2-propanol), which was combined with Ga(Me)3 [33]. This complex is nearly identical to that formed by MEL with Ga(Me)3. 

We found a solution with new, doubly promoted platinum catalysts on silica and reported their scope and limitations for the synthesis of various aniline derivatives (ref. 5). In the following communication we describe the development of the most effective catalyst using as model reaction the N-alkylation of 2-methyl-6-ethylaniline with methoxy-2-propanol. 

The N-alkylation of 2-methyl-6-ethylaniline (MEA) with methoxy-2-propanol (MOIP) was investigated in the same flow microreactor under atmospheric pressure. Feed MEA MOIP = 0.5 (3 ml/h) and hydrogen (4,7 ml/min). The reaction product was condensed in a cooling trap. Each catalyst was tested for 24 h and 7 samples were collected and analyzed separately by GLC on a fused silica capillary column with methylsilicon fluid (Hewlett Packard) as stationary phase. 

Butylene Glycol Ethers. Several butylene glycol ethers are known and described in the literature.

Deprotection of MEM and MOM ethers. Methoxyethoxymethyl and methoxy-methyl ethers are cleaved to the alcohol by this reagent in high yields. Either 2-butanone or 2-methyl-2-propanol is recommended as solvent. The procedure is particularly useful for cleavage of ethers of allylic alcohols, for which ZnBr, and TiCh are not useful. 

The Group of contractors has proposed a number of candidate solvents methanol, isobulyl methyl ketone and l-methoxy-2-propanol. In relatively short R D projects these candidates will be evaluated using a number of selection criteria that were proposed by the group of contractors. These selection criteria are ...

Although the process is general, for the specific addition process shown in Scheme 8.62, that is, the addition of methanol (methyl alcohol, CH3OH) to 2-methyloxacyclopropane (2-methyloxirane, propylene oxide) (Table 8.6, item 22), it is seen that the acid-catalyzed reaction occurs by a mixture of what appears to be (substrate dependent) SnI and Sn2 processes with the protonated oxygen of the oxirane serving as the leaving group. As shown, both 2-methoxy-l-propanol and l-methoxy-2-propanol are obtained. 

Also obtained by photo-oxidative fragmentation of 2-methyl-l-(4-methoxy phenyl)- -propanol sensitized by titanium dioxide in acetonitrile in the presence of silver sulfate (18%) [8129].
