Evidence of single electron transfer in the diastereoselective synthesis of β-stannylketones

The reaction of trimethyl- and triphenylstannylpotassium with mono and disubstituted enones (1-5) in acetonitrile as solvent was studied. In a few seconds and under mild conditions these reactions lead in nearly quantitative yields either to a mixture of diastereomers or to a pure diastereomer of β-stannylketones 6-16. The reactions with triphenylstannylpotassium gave higher yields than trimethylstannylpotassium. The partial or total inhibition of the reactions by addition of a free radical scavenger (galvinoxyl) or a radical-anion scavenger (p-dinitrobenzene) leads us to believe that these reactions could follow a two-stage reaction mechanism involving an initial electron transfer step. Our results indicate that these reactions are stereoselective but certainly not stereospecific. Full 1H- and 13C-NMR data of the new β-stannylketones are given.

SEMICONDUCTOR PHOTORESIST COMPOSITION AND METHOD OF FORMING PATTERNS USING THE COMPOSITION

A semiconductor photoresist composition includes an organometallic compound represented by Chemical Formula 1, a photoacid generator (PAG), and a solvent: In Chemical Formula 1, R is a substituted or unsubstituted C1 to C20 alkyl group, a substituted or unsubstituted C3 to C20 cycloalkyl group, a substituted or unsubstituted C2 to C20 aliphatic unsaturated organic group including at least one double bond or triple bond, a substituted or unsubstituted C6 to C30 aryl group, an ethoxy group, a propoxy group, or a combination thereof; and X, Y, and Z are each independently —OR1 or —OC(═O)R2.

SEMICONDUCTOR PHOTORESIST COMPOSITION AND METHOD OF FORMING PATTERNS USING THE COMPOSITION

A semiconductor photoresist composition includes an organometallic compound represented by Chemical Formula 1, an organic acid having a vapor pressure of less than or equal to about 1.0 mmHg at 25° C., and a pKa of about 3 to about 5, and a solvent. A method of forming photoresist patterns utilizes the composition.

SEMICONDUCTOR PHOTORESIST COMPOSITION AND METHOD OF FORMING PATTERNS USING THE COMPOSITION

A semiconductor photoresist composition includes an organometallic compound represented by Chemical Formula 1, an organometallic compound represented by Chemical Formula 2, and a solvent, and a method of forming patterns using the same. When the semiconductor photoresist composition is irradiated with e.g., extreme ultraviolet light, radical crosslinking between Sn-containing units may occur via Sn—O—Sn bond formation, and a photoresist polymer providing excellent sensitivity, small or reduced line edge roughness, and/or excellent resolution may be formed.

Synthesis of 3-stannyl and 3-silyl propargyl phosphanes and the formation of a phosphinoallene

The group 14 chloropropargyls R3ECCCH2Cl (R3E = nBu3Sn, Ph3Sn, Me2PhSi, iPr3Si, nPr3Si, nBu3Si), obtained by a modified literature procedure, react with LiPPh2 to afford the novel propargyl phosphanes Ph2PCH2CCER3 in high yield, as viscous oils; (Me3Si)2PCH2CCSiPhMe2 is similarly obtained from LiP(SiMe3)2. In contrast, the reaction of PhCCCH2MgCl with ClP(NEt2)2 fails to produce a comparable propargyl phosphane, but generates preferentially (>70%) the novel phosphinoallene (Et2N)2PC(Ph)CCH2, which is characterised spectroscopically, and through its reaction with HCl. The coordination chemistry of representative phosphanes is explored with respect to platinum and palladium for the first time.

Aminostannanes and aminostannylenes containing a C,N-chelated ligand

Aminotin(II and IV) compounds {[(2,6-i-Pr-C6H 3)(H)N]-μ-(Sn)-Cl}2, {2-[(CH3) 2NCH2]C6H4}2Sn[N(H)(2,6- i-Pr-C6H3)]2 and {2-[(CH3) 2NCH2]C6H4}Sn[N(2,6-i-Pr-C 6H3)(SiMe3)] were prepared by lithium halide elimination from tin halides and corresponding lithium complexes. [(2,6-i-Pr-C6H3)(H)N]Li (1) reacts with one half of molar equivalent of SnCl2 to give {[(2,6-i-Pr-C6H 3)(H)N]-μ-(Sn)-Cl}2. The same lithium amide (1) gave with R3SnCl corresponding aminostannanes. Further reactions of these compounds with n-butyllithium gave the starting 1 and tetraorganostannanes. {2-[(CH3)2NCH2]C6H4} 2SnBr2 reacts with two equivalents of 1 to {2-[(CH 3)2NCH2]C6H4} 2Sn[N(H)(2,6-i-Pr-C6H3)]2. The dimeric heteroleptic stannylene {[(2,6-i-Pr-C6H3) (SiMe3)N](μ2-Cl)Sn}2 reacts with 2-[(CH 3)2NCH2]C6H4Li to the monomeric {2-[(CH3)2NCH2]C6H 4}Sn[N(2,6-i-Pr-C6H3)(SiMe3)]. The structure in the solid state and in solution and reactivity of products is also discussed. The unique decatin cluster has been isolated by hydrolysis of {[(2,6-i-Pr-C6H3)(H)N]-μ-(Sn)-Cl}2. The structure of some compounds was also evaluated by theoretical DFT methods.
