One‐Pot Procedure for the Synthesis of 1,5‐Benzodiazepines from N‐Allyl‐2‐bromoanilines
TL;DR: A new one-pot procedure that includes an initial titanium-catalyzed intermolecular hydroaminoalkylation of N-allyl-2-bromoanilines with N-methylanilines and a subsequent intramolecular Buchwald-Hartwig amination directly gives access to pharmacologically relevant 1,5-benzodiazepines.

A Practical and Inexpensive One-Pot Synthesis of Bis(indenyl)dimethyltitanium with Aqueous Workup Procedure
TL;DR: In this paper, a reproducible multi-gram synthesis of bis(indenyl)dimethyltitanium is presented, which relies on a one-pot conversion of inexpensive indene, methyllithium, and titanium tetrachloride to [Ind2TiMe2] and a convenient and quick aqueous workup protocol.

An (Aminopyrimidinato)titanium Catalyst for the Hydroamination of Alkynes and Alkenes.
TL;DR: In this paper, a new (aminopyrimidinato)titanium complex has been synthesised from inexpensive and easily accessible 2-(tert-butylamino)pyrimidine and [Ti(NMe2)4] and used as a catalyst for the intermolecular hydroamination of alkynes as well as the cyclization of aminoalkenes.

TL;DR: In this article, 2-Methylcyclohexyl- or 2-methylcyclopentylamines are obtained as mixtures of trans- and cis-diastereomers.
Intermolecular hydroaminoalkylation of alkenes and dienes using a titanium mono(formamidinate) catalyst
TL;DR: The corresponding reactions, which have never been achieved with titanium catalysts before, take place with excellent regioselectivity and in addition, corresponding reactions of 1,3-butadienes with N-methylbenzylamine are also described for the first time.
