Carbonylation catalytic

Pd(II) salts promote the carbonylation of organomercury compounds. Reaction of phenylmercury chloride and PdCh under CO pressure affords benzophenone (429)[387]. Both esters and ketones are obtained by the carbonylation of furylmercury(Il) chloride in alcohol[388]. Although the yields are not satisfactory, esters are obtained by the carbonylation of aryl- and alkylmercuryfll) chlorides[389,390]. One-pot catalytic carbonylation of thiophene, furan, and pyrrole (430) takes place at the 2-position via mercuration and transmetallation by the use of PdCb, Hg(N03), and CuCl2[391]. [Pg.83]

MMA from Propyne. Advances in catalytic carbonylation technology by Shell researchers have led to the development of a single-step process for producing MMA from propyne [74-99-7] (methyl acetylene), carbon monoxide, and methanol (76—82). [Pg.252]

Hydroformylation. Probably the best known catalytic carbonylation reaction is the hydroformylation, or 0x0 reaction, for producing aldehydes and alcohols from carbon monoxide, hydrogen, and olefins (eq. 9) (36). [Pg.51]

Adipic acid may be produced by a liquid-phase catalytic carbonylation of butadiene. A catalyst of RhCl2 and CH3I is used at approximately 220°C and 75 atmospheres. Adipic acid yield is about 49%. Both a-gul-taric acid (25%) and valeric acid (26%) are coproduced ... [Pg.257]

A convenient procedure for catalytic carbonylation of bromooxazines (520) giving rise to previously unknown methoxycarbonylmethyl-substituted oxazines (525) in good yields (538) deserves note, all the more because this is the first example of catalytic C,C-coupling reactions of ethers of a-halo substituted oximes. [Pg.706]

The objective was to engineer a catalytic carbonylation-amination-Michael addition cascade employing carbon monoxide (1 atm). This cascade, if viable, could, conceptually, proceed via either of two pathways (Scheme 9). [Pg.89]

More recently, using the cyclometallated iridium C,(7-benzoate derived from allyl acetate, 4-methoxy-3-nitrobenzoic acid and BIPHEP, catalytic carbonyl crotylation employing 1,3-butadiene from the aldehyde, or alcohol oxidation was achieved under transfer hydrogenation conditions [274]. Carbonyl addition occurs with roughly equal facility from the alcohol or aldehyde oxidation level. However, products are obtained as diastereomeric mixtures. Stereoselective variants of these processes are under development. It should be noted that under the conditions of ruthenium-catalyzed transfer hydrogenation, conjugated dienes, including butadiene, couple to alcohols or aldehydes to provide either products of carbonyl crotylation or p,y-enones (Scheme 16) [275, 276]. [Pg.122]

An exceptionally simple procedure was developed for the catalytic carbonylation of chloroarenes using [PdCl2(PCy3)] as catalyst. According to this method the neat chloroanene, e.g. m-chlorotoluene and the catalyst are stirred with 20 % (w/w) aqueous KOH at reflux temperature with bubbling CO. The benzoic acids are extracted from the aqueous phase after... [Pg.152]
