Palladium pincer-complex-catalyzed selenylation of propargyl-, allyl-, benzyl-, and benzoyl halides could be achieved under mild reaction conditions employing trimethylstannylphenylselenide as selenylating agent. This reaction has a high functional group
Studies on the regio- and stereoselectivity of halohydroxylation of 1,2-allenyl sulfides or selenides
Ma, Shengming,Hao, Xueshi,Meng, Xiaofeng,Huang, Xian
, p. 5720 - 5724 (2007/10/03)
It was observed that the halohydroxylation of 1,2-allenyl sulfides or selenides with Br2 (CuBr2 or NBS) or I2 and water demonstrated a fairly good regioselectivity (i.e., the C=C bond that is remote from the S or Se atom w
SELECTIVE ONE-POT SYNTHESIS OF ALLENYL PHENYL SELENIDE AND 1-(PHENYLSELENO)PROPYNE. ROLE OF SODIUM BENZENESELENOLATE AS A BASE IN DMF

, p. 1105 - 1110 (2007/10/02)
The reaction of excess sodium benzeneselenolate with propargyl bromide in DMF-THF at room temperature produced allenyl phenyl selenide or 1-(phenylseleno)propyne selectively, depending only on the reaction time.

Selenium--Stabilized Anions. Preparation of α,β-Unsaturated Carbonyl Compounds Using Propargyl Selenides. Synthesis of (+/-)-7-Hydroxymyoporone

The reaction of alkyl halides, carbonyl compounds, and trimethylsilyl chloride with the mono- and dianion (1) prepared by deprotonation of phenyl propargyl selenide with lithium diisopropylamide gives 1- or 3-monosubstituted or 1,3-disubstituted propargyl selenides (3a).Oxidation to selenoxides (3b) results in rearrangement to 2-(phenylseleno)-1,3-disubstituted propenones.The rate of rearrangement of propargyl selenoxides increases dramatically when the phenyl group is replaced by a 2-nitrophenyl group, and an intermediate allenyl selenate ester (7c) can be observed by low-temperature NMR.By appropriate modification of oxidation conditions, modest yields of 2-iodopropenes (e.g., 10) or the selenium-free enones or enals can be obtained.A synthesis of (+/-)-7-hydroxymyoporone (15) and its epimer has been carried out by using the dianion 1 to assemble the carbon skeleton.The preparation of α-lithioallenyl phenyl selenide (26) has been accomplished, and its reaction with electrophiles has been studied.
