AlRg groups. The latter assumption is favored by the experience that incomplete reaction of the silanol groups occurs always with trimethyl-silyl chloride. This is caused by steric hindrance (219, 220). Diisobutyl aluminum groups are at least as bulky as trimethylsilyl groups. Therefore, since one aluminum atom is bound for every silanol group, a smaller ratio than two of alkyl groups to aluminum must prevail. No carbon determinations have been made, unfortunately.

Numerous procedures have been reported for the synthesis of iV-protected-a-amino aldehydes [78]. The A-protected a-amino aldehydes can be prepared either by oxidation of the corresponding A-protected j8-amino alcohols with oxidants such as pyridinium dichromate [79,80] or SOs-pyridine-di-methyl sulfoxide (DMSO) [81] or under Swem conditions [DMSO-oxalyl chloride-A,A-diisopropylethylamine (DIEA)] [81-83], by reduction of esters with diisobutyl aluminum hydride (DIBAL) [84], by reduction of A,A-disubstituted amides [85-87], by reduction of urethane-protected A-carboxy-... 

Alkyl aluminum compound n. Any of a family of organo-aluminum compounds widely used as catalysts in the Ziegler-process polymerization of olefins. Members include trialkyl compounds such as triethyl-, tripropyl-, and triisobutyl aluminums alkyl aluminum hydrides such as diisobutyl aluminum hydride and diethyl aluminum hydride and alkyl aluminum halides such as diethyl aluminum chloride. 

V<3-pyridylmethyl)dibenzylamine (IX-228, Rj = R2 = C6H5CH2). Diisobutyl aluminum hydride has also been used, as in the preparation of 3-diethylaminomethylpyridine (IX-227, R, = R2 = C2HS) from iV,A -diethyl-nicotinamide (IX-228, Rj = R2 = C2HS). 7-Methoxy-l-naphthylacetyl chloride reacts with 2-aminopyridine to give the corresponding amide, which is reduced by lithium aluminum hydride to IX-229. ... 

The requisite functionalized monomer 5 was prepared by the atation of the published syndiesis of HMDB (5-5). First, 2-butyne was dimerized in the presence of aluminum chloride and treated in situ with ethyl tetrolate to provide ethyl pentamethyl Dewar benzoate. (3). Reduction of 3 with diisobutyl aluminum hydride produced the alcohol 4, which was esterified with methacryloyl chloride to generate monomer 5. The desired copolymers of 5 with various methacrylic esters were synthesized by solution polymerization using an azo initiator, yielding the 10/90 copolymers 6.
