Green synthesis of 2, 2-dialkoxy acetophenone derivative

The invention provides green synthesis of a 2, 2-dialkoxy acetophenone derivative (1), and the structure of the 2, 2-dialkoxy acetophenone derivative (1) is shown as follows, wherein R is alkyl, and R1 is one or more of alkyl, halogen, alkoxy, N, N-dialkylamine or benzoring. According to the method, the 2, 2-dichloroacetophenone derivative, alcohol and alkali are taken as raw materials and are subject to heating and stirring to obtain a target product 2, filtering is performed after the reaction is completed, filtrate is concentrated, and a high-yield and high-purity product can be obtained. The method has the advantages of simple operation, few byproducts, and no generation of any toxic or environmentally harmful substances in the reaction. A new synthesis method is provided for the target product 1.

Unusual tandem oxidative C-C bond cleavage and acetalization of chalcone epoxides in the presence of iodine in methanol

An unusual reaction of chalcone epoxides is observed where chalcone epoxides on heating with iodine in methanol leads to α,α- dimethoxyacetophenones, through C-C bond cleavage followed by acetalization of the formyl group. The process occurs through ring

Efficient preparation of α-ketoacetals

The Weinreb amides 2a,b were prepared from the a,a-dimethoxyacetic acids 1c,d. A number of representative nucleophilic additions (RMgX and RLi) on 2 afforded a-ketoacetals 3a-j in 70-99% yield. These compounds represent a versatile arrangement of functional groups of significant synthetic value, as demonstrated in the synthesis of (±)-salbutamol.

Synthetic use of poly[4-(diacetoxyiodo)styrene] for organic reactions

Poly[4-(diacetoxyiodo)styrene] is sufficiently reactive for the iodination of aromatics, the oxidative 1,2-aryl migration of alkyl aryl ketones, the α-hydroxylation of ketones, and the oxidation of hydroquinones and sulfides similarly to (diacetoxyiodo)benzene. Here, those reactions with poly[4-(diacetoxyiodo)styrene] are very useful because of the simple operation; thus, filtration gives the crude products and recovered poly(4- iodostyrene), and then poly[4-(diacetoxyiodo)-styrene] can be regenerated by oxidation of the recovered poly(4-iodostyrene), which are reused for the same reactions.

Liquid photoinitiator mixtures

Liquid highly active photoinitiators are obtained by dissolving a solid photoinitiator of the titanocene type in liquid photoinitiators of the acetal or ketal type. The liquid mixtures have a long dark storage stability.

Oxygen-containing titanocenes, and the use thereof

Titanocenes of the formula I STR1 in which R1 are cyclopentadienyl? groups and R2 and R3 are aromatic radicals which are substituted in both ortho-positions by fluorine and, in addition, are substituted by an acyloxy group are suitable as photoinitiators for the photopolymerization of ethylenically unsaturated compounds.

(Benzotriazol-1-yl)methoxymethyl anion: A novel methylal anion equivalent

The title anion readily reacts with a variety of electrophiles to give adducts which, upon treatment with methanol in the presence of p-toluenesulfonic acid, afford the corresponding α-functionalized dimethyl acetals.

Titanocenes, the use thereof, and n-substituted fluoroanilines

Titanocenes containing two 5-membered cyclodienyl gropus, for example cyclopentadienyl, and one or two 6-membered carbocyclic or 5- or 6-membered heterocyclic aromatic rings which are substituted by a fluorine atom in at least one of the two ortho-positions to the titanium-carbon bond and contain, as further substituents, a substituted amino radical, are suitable as photoinitiators for radiation-induced polymerization of ethylenically unsaturated compounds.

Titanocenes, the use thereof, and N-substituted pyrroles

Titanocenes containing two 5-membered cyclodienyl groups, for example cyclopentadienyl, and one or two 6-membered carbocyclic or 5- or 6-membered heterocyclic aromatic rings which are substituted by a fluorine atom in at least one of the two ortho-positions to the titanium-carbon bond and contain, as a further substituent, unsubstituted or substituted 1-pyrryl, are suitable as photoinitiators for radiation-induced polymerization of ethylenically unsaturated compounds.

Novel nitrogen-containing titanocenes, and the use thereof

Titanocenes of the formula I STR1 in which R1 are cyclopentadienyl? groups and R2 and R3 are aromatic radicals which are substituted in both ortho-positions by fluorine and, in addition, are substituted by a pyrrylalkyl group, amidoalkyl group or imidoalkyl group, are suitable as photoinitiators for the photopolymerization of ethylenically unsaturated compounds.
