摘要:A method for preparing an α-halo enal or enone from an unprotected propargyl alcohol and an electrophilic halogen source catalyzed by the combination of a gold catalyst complex and a metal co-catalyst complex is disclosed. The method can be further enhanced by addition of an additive that facilitates suppression of a des-halo derivative.

标 题:Transport of ethyne in form of α-alkynols as ethyne precursors
发明人：WILDERMANN ANGELA; BONRATH WERNER; HELLMANN GUNTHER
权利人:DSM IP ASSETS BV
摘要:The present invention relates to a new method for a safe transport of ethyne in form of α-alkynols as precursors for ethyne. The new method comprises three steps. In a first step the synthesis of the α-alkynol(s) is performed by reacting ethyne with (a) carbonyl compound(s). The second step comprises the transport of the resulting α-alkynol(s) in a safe manner, whereas the safety requirements for this transport are not as high as for ethyne because α-alkynol(s) are normally classified for transportation as hazardous class 3. In the third step the α-alkynol(s) can be cleaved and the ethyne and the carbonyl compound(s) can be obtained in the cleavage reaction and can be separated to yield pure products for further applications.

标题 :Manufacture of 2-(alkyl, alkenyl or alkynyl) 3-carbalkoxyalkyl ketones from alpha, beta-unsaturated ketones
发明人：GREENE ANDREW E; CRABBE PIERRE
权利人:CHON CORP
摘要:The copper enolate of 3-allylcyclopentanone is alkylated with an alkyne so as to form the 2-alkynyl, 3-allylcyclopentanone which is then subjected to ozonolysis and oxidative cleavage to form 2-alkynylcyclopentan-3-one-1-yl alkylcarboxlic acid. The acid can be esterified to form a 2-alkynyl-3-carbalkoxyalkyl ketone which, in turn, can be hydrogenated to convert the alkynyl moiety to alkenyl or alkyl moieties. The procedure is particularly useful in the synthesis of methyl dl-jasmonate, dehydrojasminate and dihydrojasmonate.
